{"version":"1.0","type":"rich","title":"Assignment-2","description":"This pie chart visualizes the distribution of fish species from a CSV dataset loaded via `d3.csv`. It uses `d3.nest()` to count occurrences per species, then `d3.pie()` and `d3.arc()` to generate the chart geometry, with `d3.scaleOrdinal` and `d3.schemeCategory10` for color encoding. The SVG rendering includes an interactive legend, and the code demonstrates a reusable pattern for pie charts with D3 v6.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9111a89239b84cd99bf061c2f46fddef?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
