{"version":"1.0","type":"rich","title":"Activity 7.1","description":"This pie chart visualizes the distribution of total counts across different travel modes from a CSV dataset. The data is loaded via `d3.csv` and aggregated by the 'Mode' column, with each slice's size proportional to its 'Total' value. The chart uses `d3.pie` and `d3.arc` to generate the arcs, which are rendered as SVG paths with a categorical color scale from `d3.scaleOrdinal`. A legend, built with the same color mapping, displays each mode and its corresponding total value alongside the chart.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/59d097cee6bd4288bf911d2d316517f3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
