{"version":"1.0","type":"rich","title":"Grouped BarChart","description":"A grouped bar chart compares five categories of support for Colombian political figures using data from a CSV file. The visualization uses D3 v3 with SVG rendering, grouping bars by candidate and coloring each support type via a categorical scale. Animated transitions initially drop bars from zero before settling into their final positions, and hover interactions temporarily highlight bars in yellow. The code demonstrates ordinal scales, nested data layouts, axis generation, and chained transition behavior, with a legend clarifying category colors.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-d8f36edd493140cf4de52934fa51a53d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
