{"version":"1.0","type":"rich","title":"Blank SVG","description":"This example displays a blank canvas and logs the D3 library to the console. It defines a main function that declares a single `fontSize` variable but does not render any visual content. The code imports the `select` function from D3 and uses the D3 library loaded via a global script in `package.json` for visualization. The HTML page contains a div with the id \"canvas\" where a chart would normally be placed, but no drawing occurs.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/04e7dcdea5254e7d8d8180a822e3c840?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
