{"version":"1.0","type":"rich","title":"d3 and canvas - the bind and the draw","description":"This example demonstrates how D3’s data join can drive canvas rendering through a custom HTML element as an intermediate container. The visualization displays a grid of colored cells, with the number of cells controlled by a text input, and animates their appearance. The code binds data to custom elements using D3’s `selectAll`, `enter`, and `merge`, then draws each cell’s position and fill style onto a 2D canvas context, using a `d3.scaleSequential` color scale and `d3.timer` for animation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6b2f82fb5a8d44a4bc047452097f3b16?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
