{"version":"1.0","type":"rich","title":"d3_firsttask","description":"This example visualizes a dataset of CSS named colors as a pie chart, where each slice represents a color and is filled with its corresponding RGB hex value. The code uses React with hooks to asynchronously load CSV data from a gist via `d3.csv`, then builds the chart using `d3.pie` and `d3.arc` in an SVG. Each slice is rendered as a path with equal value weighting, and the entire pie is centered within a fixed 960×500 viewport.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
