{"version":"1.0","type":"rich","title":"Retail Visitors Rate in the Pandemic","description":"This sunburst chart visualizes retail visitor rates during the pandemic, with each radial segment representing a category and its size proportional to visitor counts. The color scale maps values from red through green to magenta using d3.interpolateHsl. Built with d3.partition and d3.hierarchy, the visualization animates arc transitions using d3.arc and d3.transition. Interactive mouseenter, mouseleave, and click events on transparent overlay arcs log the selected segment’s path to the console. The SVG renders data parsed from inline JSON, with a lightsteelblue background.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2cf197a1d6204a87a34ee85ea900a02b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
