{"version":"1.0","type":"rich","title":"Activity - 9_Question - 1","description":"A pie chart visualizes population distribution across continents from a CSV file, using D3 v5 loaded via UNPKG. The code parses numeric population values, applies an ordinal color scale from `d3.schemeCategory10`, and constructs arcs with `d3.arc()` and `d3.pie()`. An SVG legend maps each color to its continent. The example also demonstrates importing local ES6 modules and styling with external CSS, though the main message is rendered through the chart.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b66b6705b3db46e5acd6c83fdb5b8aef?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
