{"version":"1.0","type":"rich","title":"D3 starter","description":"This example demonstrates a simple SVG-based visualization using D3 v7 within a React-compatible setup, rendering 100 horizontal bars across the full viewport width, each 10 pixels tall. The bars are created with `d3.range` and `svg.selectAll(...).join('rect')`, masked by a circular `mask` element with the ID `circle-mask`. The mask, appending a white background, visually clips the bars through SVG masking. The code imports `select` and `range` from the D3 library, though the HTML page is minimal and the JavaScript is designed to run in a browser environment.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/142ebb9492604ac98315bd164a5cc4a9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
