{"version":"1.0","type":"rich","title":"d3 choropleth map","description":"This choropleth map visualizes the spread of COVID-19 cases over time, with an animating date slider and play/pause controls. The map uses d3.geoEckert5 projection, d3.geoPath, and TopoJSON, with color scales from colorbrewer and d3-scale-chromatic to shade regions by case counts. A draggable slider, built with d3.drag and d3.timeScale, shows daily case data from January to July 2020, while a legend and graticule provide spatial context.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/753142c8e54f4b9699e596096f22bb72?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
