{"version":"1.0","type":"rich","title":"HTML Starter","description":"This example displays a blank red square rendered as an SVG canvas, demonstrating the minimal setup required to combine HTML, D3, and React in a visualization project. The code includes a 960x500 SVG element and uses d3.select to target it, then applies a red background via style. It serves as a bare-bones starter template, referencing d3.v5 loaded from a CDN. The visualization itself shows no data or marks, only the styled empty SVG, emphasizing the foundational structure for building more complex charts.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/fa1641e7f657432a9d18a257e3874668?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
