{"version":"1.0","type":"rich","title":"Grouped Bar Chart","description":"This example shows the ten most populous countries grouped by continent, with horizontal bars scaled by population. Each continent appears as a separate band containing its countries, with a title and shared x-axis. The visualization is built with React and D3 v6, using `scaleBand` for country placement, `scaleLinear` for population values, and SVG rectangles rendered via a custom `Marks` component. Data is loaded asynchronously from a CSV file using D3's `csv` method.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/48a4907dec214a13b58751d63c477edf?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
