{"version":"1.0","type":"rich","title":"Zoomable treemap template","description":"Built with D3.js v3 and jQuery, this interactive visualization presents education resource data as a zoomable treemap. The code uses `d3.layout.treemap` to hierarchically arrange rectangles by value, colored via `d3.scale.category20c`, with click-to-transition zooming between parent and child nodes. Data is loaded from a JSON array of entries containing subject, region, subregion, and count values, which the treemap aggregates and lays out recursively. The SVG renders responsive rectangles and a grandparent breadcrumb header, demonstrating a reusable template for hierarchical exploration.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/117ba16124b64b27851ab00b9d73050d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
