{"version":"1.0","type":"rich","title":"Activity 7.1 Question 1","description":"This example shows the distribution of car horsepower values as an interactive pie chart. It groups the data into ten horsepower bins using `d3.histogram`, then visualizes each bin’s count with `d3.pie` and `d3.arc` in an SVG. A categorical color scale (`d3.scaleOrdinal` with `d3.schemeCategory10`) colors each slice, and a separate HTML legend displays the bin ranges. The data is loaded asynchronously via `d3.csv` from a GitHub Gist, demonstrating local ES6 module imports and D3’s histogram, pie, and arc APIs.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/dcb2ed010ce041c48657f48360f2072d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
