{"version":"1.0","type":"rich","title":"Travel HuBei Distribution Chart","description":"This chart displays the distribution of travel history among COVID-19 cases across Chinese provinces, using stacked horizontal bars to compare counts of patients with and without travel history. Users can toggle between raw counts and percentage-normalized views, which triggers animated transitions that rescale the axes and recalculate bar heights. The visualization is built with D3.js version 3.5.6, utilizing the `d3.layout.stack` API for stacking, `d3.svg.axis` for axes, and SVG for rendering the interactive chart.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/66be12b140e1414a9cc43c73e7132d14?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
