{"version":"1.0","type":"rich","title":"lines","description":"This example shows monthly COVID-19 case counts from the New York Times rolling-averages dataset as a line chart with circular markers, rendered as SVG using React and D3 v7. The code aggregates daily data by month using `d3.rollup` and `d3.sum`, scales time and linear values with `d3.scaleTime` and `d3.scaleLinear`, and draws the line with `d3.line`. A `d3.brushX` brush overlay is attached to the chart, logging selected date ranges to the console, while axes are generated by custom React components.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7fac4f699b1342e2ad031720c414beab?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
