{"version":"1.0","type":"rich","title":"My Line Chart","description":"This line chart visualizes a user’s 2020 internet usage in gigabytes over time, with a highlighted band marking usage above 100 GB. The D3 v5 code loads CSV data, uses `d3.scaleTime` and `d3.scaleLinear` for axes, and draws the line with `d3.line`. It includes interactive tooltips triggered by `mousemove` events on a transparent overlay, using `d3.scan` to find the closest data point. The SVG rendering features custom axes, labels, and a dashed vertical guide.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f7d4ed9845e14ef083180e14a894f7b7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
