With the development of Big Data research, visualization and visual analysis have gradually become research hotspots in the field of big data, and have been rapidly developed, playing an increasingly important role in the era of big data, and the application prospects are increasingly broad.
Visualization and visual analysis are the basis for understanding the intrinsic laws and models of complex phenomena, from biophysical multimodal information to climate change across centuries, from day and night in international metropolises to high-precision simulation of pneumatic aircraft. Visualization, a discipline that spans traditional boundaries, can quickly and efficiently streamline and refine data streams to provide users with deeper information. This forum invites many well-known experts in the field of visualization at home and abroad to introduce key technologies and typical applications of big data visualization and visual analysis from multiple perspectives, and explore how to further actively promote the innovation and development of technology and disciplines.Speakers:

Title: Visual Exploration of Big Data in Astrophysics
Abstract: Astrophysics can be regarded as the ultimate remote sensing because no one can travel to see real heavenly bodies located far from the Earth. The only option for astronomers is to observe and study a variety of signals emanating from the distant bodies. This might lead to their enthusiasm for data visualization, compared to ones in other disciplines. Indeed, astrophysics relies heavily on the values of observed data visualization and analysis. In this talk, an overview of the latest research results from our collaborative research projects with astronomers will be given, including asymmetric biclustering of multivariate data for correlated subspace mining and its application to supernovae categorization, TimeTubes for visually extracting feature polarization variations from long-sequences of observed blazar datasets, and aflak as a novel visual programming environment to conduct fine-grained transformations, filtering and visual analyses on multispectral astrophysical observations.

Title: Research on Visualization Method Based on Map as Metaphor
Abstract: Visual analysis is an effective means of analyzing big data and is receiving increasing attention. As a very representative method in visualization, maps are an effective means of human geography and phenomena in generalization and symbolization. Since the Stone Age, humans have begun to make maps. Here, we discuss the case of drawing various semantic maps through data. At the same time, we will further discuss the visualization of maps as metaphors for virtual cyberspace beyond ordinary real physical space, with scientific observation data, high-dimensional data, Data such as cyber security and social media are targeted.

Title:Full space augmented reality visualization engine
Abstract:Aiming at the major needs of the multi-modal spatio-temporal big data exploratory analysis of the ternary space fusion of human and physical objects in smart cities, the characteristics of human spatial cognition and artificial intelligence and augmented reality are fully considered. The paper introduces data (multi-source heterogeneous, high-dimensional, dynamic)-environment (complex storage and painting environment and multi-granularity analysis model) - task (diversity diversification, multi-level, fuzzy) integration of full-space augmented reality visualization engine. The article puts forward the concept of "super brain" with spatial thinking as the center, defines semantic-level visual variables, and establishes an adaptive visualization mechanism for task perception. The article explores its potential application value in combination with typical application cases such as intelligent facility management and public safety emergency response.

Title: Visual analysis of urban big data
Abstract: With the rapid development of urbanization, the data generated by the city shows an explosive growth trend, resulting in urban big data. The effective analysis of this data is the core of building a smart city, with a very broad business scene, research value and the prospect of the application. However, urban big data has many characteristics such as multi-source, massive and high-dimensional, which makes it difficult to analyze and reason about such data. Visual analysis is an important means of urban big data analysis by providing interactive human-machine interface, combined with automatic data mining algorithms and human intuition, experience and knowledge to assist in data analysis, reasoning and decision-making. This report begins with a brief introduction to the basic concepts and methods of urban big data and visual analysis, reports on the latest developments at home and abroad and their future prospects, and introduces work in related fields through multiple cases such as urban site selection and planning.
