With the rapid development of information technology and the significant enhancement of data collection capabilities, human society is entering an unprecedented era of big data. Massive, diverse, and high-velocity data streams are reshaping the operational modes and decision-making methods across various industries [1]. However, data itself does not equate to insight; how to extract valuable information from complex data has become a key issue that urgently needs to be addressed. In this context, data visualization, as a bridge connecting raw data and human cognition, is playing an increasingly important role. Data visualization effectively reveals hidden patterns, trends, and associations in data by transforming abstract data into intuitive graphical expressions, thereby enhancing human cognitive abilities and decision-making efficiency [2]. In recent years, with the continuous advancement of big data analysis technologies, data visualization also faces new opportunities and challenges. Traditional static charts and simple interactive visualizations can no longer cope with massive, high-dimensional, and dynamic big data environments, prompting researchers to continuously explore new visualization theories and technical methods [3]. Meanwhile, the development of emerging technologies such as artificial intelligence and virtual reality has provided a broad space for innovation in data visualization. In fields such as business intelligence, scientific research, and public decision-making, data visualization is playing an increasingly important role, driving data-driven decision-making models and innovative practices. However, how to achieve efficient, accurate, and insightful data visualization in the big data environment still faces many theoretical and technical challenges. Based on this, this study aims to systematically review the current applications of data visualization in big data analysis, discuss possible future development trends, and provide references and insights for promoting the innovative development of data visualization theory and practice.
This paper is structured as follows: Section 2 explores the evolution of big data visualization techniques; Section 3 analyzes the applications of big data visualization in business intelligence, scientific research, and public policy; Section 4 looks at future trends; and finally, Section 5 concludes the paper.
2. Theoretical Foundations and Technological Evolution of Data Visualization
2.1. Core Theories of Data Visualization
The core theoretical foundations of data visualization stem from research findings in human visual perception and cognitive science. Gestalt psychology theory points out that humans tend to perceive visual information holistically, providing important guidance for designing effective visualization charts. Information processing theory emphasizes the advantages of visual channels in information transmission, explaining why graphical expressions can convey complex information more quickly than text [4]. Additionally, visual attention theory helps us understand how to guide users to focus on key information and avoid visual clutter. Building upon these theoretical foundations, theories such as Tufte’s data-ink ratio and Cleveland and McGill’s graphical perception theory have further refined the design principles of data visualization [5]. These theories collectively construct the scientific basis of data visualization, guiding visualization designers on how to select appropriate visual elements and encoding methods to maximize information transmission efficiency and cognitive effectiveness. With the advent of the big data era, these classic theories are continuously being validated, expanded, and reinterpreted to adapt to new data environments and user needs.
2.2. Visualization Challenges in the Big Data Era

Notably, the rise of open data visualization platforms is promoting the transparency of government decision-making and public participation, allowing ordinary citizens to directly access and explore public data and participate in policy discussions. As shown in Figure 2, multi-level data visualization applications are reshaping the public decision-making process.
4. Future Trends in Data Visualization
4.1. Interactive and Real-time Visualization Technologies
Interactive and real-time visualization technologies are becoming important development directions in the field of data visualization, driven primarily by increasing data complexity and diversifying user needs [9]. With the advent of the big data era, static visualization expressions can no longer meet the demands of in-depth analysis. Interactive visualization allows users to actively explore data, examining it from different angles and granularities through operations such as zooming, filtering, and drilling down to discover potential patterns and insights. For example, in financial analysis, interactive time series visualization tools allow analysts to dynamically adjust time spans, compare correlations between different indicators, and quickly identify anomalies and trends. This interactive capability not only improves the efficiency of analysis but also stimulates users’ desire to explore, promoting deeper data understanding. Meanwhile, real-time visualization technology is addressing the challenge of continuous data updates, ensuring the timeliness and coherence of visualization. This is particularly important in fields such as the Internet of Things and social media analysis, requiring visualization systems to process data streams in real-time, dynamically update views, and reflect the immediate state of data.
In the future, the development of interactive and real-time visualization technologies will focus more on user experience and intelligence. We may see more adaptive interactive visualization systems combined with artificial intelligence, capable of automatically adjusting visualization strategies based on users’ operational behaviors and points of interest, providing more relevant information and insights [10]. For instance, systems might learn users’ exploration patterns, predict the next possible analysis needs, and proactively provide corresponding visualization views or interaction options. Furthermore, with the development of edge computing and 5G technology, the response speed and data processing capabilities of real-time visualization will be significantly improved [11]. This will enable more complex real-time data analysis, such as real-time monitoring and anomaly detection of large-scale sensor networks. Another trend worth noting is collaborative visualization analysis, allowing multiple users to interact and collaborate simultaneously, which is particularly important for cross-departmental and cross-regional team analysis. Overall, the advancement of interactive and real-time visualization technologies will greatly enhance the depth and breadth of data analysis, providing decision-makers with more timely and comprehensive data insights.
4.2. AI-Enhanced Data Visualization
Artificial intelligence technology is profoundly changing the landscape of data visualization, from automation to intelligence, injecting new vitality into visualization analysis. Machine learning algorithms are being used to automatically generate and optimize visualization charts. By analyzing data characteristics and user preferences, AI systems can recommend the most suitable visualization schemes, reducing users’ cognitive burden [12]. For example, natural language processing technology enables users to generate complex visualization charts through natural language descriptions, greatly lowering the technical threshold for visualization. AI technology is enhancing the explanatory power of visualization. By integrating machine learning models, visualization systems can not only show “what it is” but also explain “why it is,” helping users understand the causal relationships behind the data. This explanatory visualization is particularly important for analyzing complex systems, such as in medical diagnosis and financial risk assessment. AI-driven anomaly detection and predictive visualization are becoming trends that are capable of automatically identifying abnormal patterns in data and highlighting them through visualization, alerting users to pay attention. This proactive data insight is of significant value for real-time monitoring and decision support systems.
As shown in Figure 3, AI-enhanced data visualization covers the entire process from data preprocessing to insight generation. In the future, with the development of deep learning and reinforcement learning technologies, we may see more intelligent and personalized visualization systems. These systems will be able to learn users’ analysis habits, predict information needs, and provide proactive visualization support. For example, systems may automatically adjust the complexity and focus of visualization based on the user’s role, task context, and past behavior, ensuring the relevance and comprehensibility of information. Another important trend is AI-assisted data storytelling, where systems can automatically extract key insights from complex datasets and generate coherent visualization narratives, helping non-professional users better understand and communicate data insights. AI technology will also drive the cross-modal integration of visualization, such as comprehensively analyzing and visualizing multiple data sources including text, images, and voice, providing a more comprehensive information perspective. It is worth noting that as AI applications in visualization deepen, maintaining the balance of human-machine collaboration and ensuring AI enhances rather than replaces human insight will become an important research topic.

4.3. Immersive and Multi-Sensory Data Visualization
Immersive and multi-sensory data visualization represent cutting-edge development directions in data visualization, aiming to enhance data understanding and insight through richer sensory experiences [13]. The advancements in virtual reality (VR) and augmented reality (AR) technologies have provided new possibilities for immersive data visualization. In complex system analysis, VR technology allows researchers to “step into” high-dimensional data spaces, exploring data relationships through body movements and gesture interactions, which can inspire new insights and creativity. For example, in molecular biology research, scientists can intuitively observe and manipulate complex protein structures through VR environments, accelerating the process of new drug development. AR technology can seamlessly integrate data visualization into real environments. For instance, in smart city management, managers can directly overlay visualizations of traffic flow, energy consumption, and other data onto real city scenes through AR glasses, achieving real-time, intuitive decision support. This contextualized visualization greatly enhances the connection between data and the real world, making abstract data easier to understand and apply.
Multi-sensory data visualization further expands the dimensions of data expression, not limited to vision but including auditory, tactile, and other sensory channels [14]. Sound can be used to express time series changes in data, such as converting stock market fluctuations into music, helping analysts identify market patterns through auditory perception. Tactile feedback can enhance the understanding of data structures, such as feeling the clustering structure or anomalies of data through force feedback devices [15]. This multi-channel data expression not only increases the bandwidth of information transmission but also provides better data access for visually impaired individuals, promoting the inclusivity of data visualization. In the future, with the development of brain-computer interface technology, we may even see visualization forms that directly interact with and understand data through thoughts, opening a new era of data comprehension. For example, directly controlling the parameter adjustments of data visualization through electroencephalogram (EEG) signals, or evaluating and optimizing visualization effects through neural feedback. This direct brain-computer interaction may greatly improve the efficiency and intuitiveness of data analysis, especially when dealing with high-dimensional complex data. However, this frontier field also faces numerous ethical and technical challenges, such as how to ensure data privacy and security, and how to balance enhanced cognition with cognitive load, all of which require in-depth research and discussion.
