Strengthening Data Linkage to Improve Visualization System for Exploratory Analysis

The objective of our study is to support user analysis of time series data in an exploratory manner. Such exploratory analysis requires repeated access to various types of information that are related to user interests, such as text and numeric data. To support such analyses, we have developed a system that visualizes temporal changes in time series data and presents the causes of those changes. In this study, we improve the design of our previous system by strengthening the linkage between graphs and articles and adding graph interactions. In addition, we conduct user experiments and evaluate the point of arrival of the system.
