{"version":"1.0","type":"rich","title":"Activity 7","description":"This example visualizes the distribution of movies rated above 8.5 by genre as a pie chart, with a custom legend using distinct D3 symbols (circles, squares, triangles, diamonds, and crosses) for each genre. It loads CSV data asynchronously via `d3.csv`, converts the relevant column to numbers, and renders the chart as SVG using `d3.pie` and `d3.arc`. The visualization uses a color scale with `d3.schemeCategory10` and includes axis labels and a title, though no axes are drawn.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/195fa10409424741af711d4c7a417503?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
