{"version":"1.0","type":"rich","title":"First D3 Test","description":"A plain red square fills the entire 400-by-400 pixel SVG viewport, with no axes, labels, or data plotted. The example demonstrates the minimal setup for a D3 visualization by selecting the SVG element with `d3.select` and applying a CSS background color directly via `.style()`. It loads D3 v5 from a CDN and uses a bundled ES module import, relying on the SVG rendering approach. This serves as a first functional test, confirming that D3 and the SVG container are correctly connected.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/361741c4ca454a62b848c46ab5ff1707?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
