{"version":"1.0","type":"rich","title":"activity7.1-2","description":"This chart displays the relationship between car horsepower and highway miles per gallon as a filled area. The code loads CSV data from a GitHub repository and parses the numeric fields. It uses D3.js v7 to create an SVG, applying a linear scale for both axes and the d3.area generator to construct the area path. Axis labels are added using d3.axisBottom and d3.axisLeft, with the chart rendered on a white, rounded background.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e6b35dbfaea943488bb113601a06d8a1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
