{"version":"1.0","type":"rich","title":"Framework","description":"This example demonstrates how to build a simple interactive framework using D3.js by modifying SVG elements in response to user input. It displays a blue rectangle centered within an SVG canvas, and clicking on the rectangle changes its fill color to green. The code uses D3 selections and the `select` and `arc` imports from the d3 module, with the `on(\"click\", ...)` method to attach the event handler. The visualization relies on D3 v5 and renders directly to SVG with dimensions of 960 by 500 pixels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
