{"version":"1.0","type":"rich","title":"Activity 7_Answer 1_D3.JS","description":"This pie chart shows the distribution of vehicle types in a dataset, with each slice colored and paired with a legend. The visualization is built using D3.js v7 and rendered as SVG, with the pie geometry computed by `d3.pie()` and drawn using `d3.arc()`. Data is loaded from a remote CSV file, aggregated with `d3.rollup()`, and colored using `d3.scaleOrdinal(d3.schemeTableau10)`. The chart includes axis labels and hover tooltips, though the code erroneously mislabels the categorical pie slices as X and Y axes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7a5090f2737145248fb3240fbf20a241?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
