{"version":"1.0","type":"rich","title":"footest","description":"This example visualizes the distribution of hair and eye colors in a dataset of 16 individuals, grouped by eye color and displayed as a multi-bar chart. The chart, built with the NVD3 library and D3 v2, renders animated SVG bars that transition over 500 milliseconds when loaded. Data is nested using `d3.nest()` to group records by the “Eye” attribute, and the chart is configured with NVD3’s `multiBarChart` model, which handles the x-axis (hair color) and y-axis (frequency) mappings. The visualization is embedded in an HTML page with jQuery for initialization.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-6208475?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
