{"version":"1.0","type":"rich","title":"HTML Starter","description":"A minimal D3.js example renders a single black circle on a 400 by 400 SVG canvas. The visualization is created using `d3.select` to target the `#chart-area` div, followed by chained `.append` calls to construct the SVG and circle elements. The circle is centered at coordinates (200, 200) with a radius of 100 pixels. This starter template demonstrates the basic structure for embedding D3 visualizations within an HTML page.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/341a71bed8b24cfab584c678f9f27b7c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
