{"version":"1.0","type":"rich","title":"Fork of Streamgraph of covid-19","description":"This streamgraph visualizes the spread of COVID-19 cases across five continents (Africa, Asia, Europe, America, Oceania) using an animated time series. The stacked area chart, rendered as SVG, uses a silhouette offset to highlight each region's contribution to the global total. Built with React and D3.js (v2), the visualization loads monthly aggregated case data from `data_monthly.csv`, with tooltips providing daily case counts on hover. The code leverages `d3.layout.stack`, `d3.svg.area`, and `d3.time.scale` for the temporal axis.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/196c2cabadc04e8a887cef4ab8bf2fb4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
