{"version":"1.0","type":"rich","title":"Activity7_Piechart","description":"This visualization shows the distribution of employees across departments using a pie chart, with each slice representing a department and sized by its employee count. The chart renders in SVG using d3.pie and d3.arc, while d3.rollup aggregates the CSV data from a GitHub gist to count records per department. A separate legend on the right maps each department to its color from d3.schemeSet3, and tooltips display the department name and count on hover.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3864c2509d524e5684644397de43ecf2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
