{"version":"1.0","type":"rich","title":"Area Chart","description":"This example visualizes the daily new COVID-19 cases in Spain over a 60-day period using an area chart. The chart combines a semi-transparent steelblue filled area with a solid line to show the trend, and includes labeled axes for dates and case counts. The data is loaded from the CSSEGISandData GitHub repository using `d3.csv`, processed by filtering for Spain and computing daily differences, and then rendered as SVG paths generated with `d3.area` and `d3.line`. Scales are created with `d3.scaleTime` and `d3.scaleLinear`, axes are drawn using `d3.axisBottom` and `d3.axisLeft`, and sparse data points are marked with circles that display a tooltip on hover.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4d0346e19b114e1eb77133f104ea4653?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
