{"version":"1.0","type":"rich","title":"D3 testing1","description":"This example draws a single SVG circle and text element using D3 v5, displaying the number \"3\" in blue. The code defines a reusable `createNumIcon` function that appends a stroked circle and a text label to an SVG canvas via `d3.select` and the `append` and `attr` methods. The circle has a fixed radius of 20 pixels and a blue stroke, while the text uses Arial font at 35 pixels. No data is loaded; the visualization is purely static and demonstrates basic SVG shape creation with D3.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
