{"version":"1.0","type":"rich","title":"example 1","description":"A red square is drawn at a fixed position on a 900 by 600 SVG canvas, created with D3 v5. The example demonstrates a reusable rectangle component defined in a separate module, which appends an SVG `rect` element with specified width, height, x, y, and fill attributes. The main script imports `select` and `arc` from D3, though only `select` is used, and imports the custom `rectangle` function. The code includes unused scaffolding for x-position arrays and scales, but the visible rendering is limited to this single static shape.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b0559a6958b04dcdbf8443dc448562dd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
