{"version":"1.0","type":"rich","title":"Vega-Lite API Part I","description":"This example visualizes CSS named colors as an arc diagram, where each color name is mapped to a radial segment and its hue determines the stroke color. A tooltip reveals the color name on hover, and the chart fills the entire browser window with a dark, high-contrast theme. The visualization is built using the Vega-Lite API, which composes a single `markArc` encoding with `fieldN` mappings for position, color, and tooltip. Data is loaded asynchronously from a CSV file via `d3.csv`, while the view is rendered as SVG using Vega, Vega-Lite, and the vega-tooltip handler.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d1068bf86584487eb9b39e081315eeef?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
