Visualization, image and interaction have all become the design directions of user interfaces in recent years. The purpose of this study is to collect the user’s perception of the chart through experiments, explore the visualization of the chart presentation, and establish the “The principle of infographic design”. This study used the Octopus web data collection software to collect travel-related social big data of Facebook fan page and produce six different types of charts (a total of ten charts) by Tableau visual software that used as the experimental chart material.
