{"version":"1.0","type":"rich","title":"DV ASSIGNMENT-2.2","description":"This example visualizes highway fuel efficiency across vehicle makes using a D3 area chart rendered as SVG. The chart maps car makes along the x-axis and their highway miles-per-gallon values along the y-axis, with a semi-transparent steel-blue area filling the region beneath the line. It fetches a remote CSV dataset, parses it with `d3.csvParse`, and uses `d3.scaleBand`, `d3.scaleLinear`, and `d3.area` to construct the visualization. Custom axis styling rotates the x-axis labels for readability, and the code demonstrates loading D3 v7 via CDN and ES6 module imports.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3ce5d30439334264b0b13b45c5cff1ba?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
