{"version":"1.0","type":"rich","title":"HTML Starter","description":"This HTML starter demonstrates the use of D3 v7 to build an SVG scatterplot with axes and summary statistics. It loads a CSV from a GitHub gist and maps quantitative columns like Horsepower, Torque, and MPG to x-position, y-position, and size, while a categorical Layout column drives color. The code uses `d3.csv`, `scaleLinear`, `scaleOrdinal`, `extent`, `mean`, and `median` APIs to process data and render marks.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/22a2ba8b771c4163b3243af9b82aecbe?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
