{"version":"1.0","type":"rich","title":"Fork of d3 and canvas - the bind, the draw\n      and the pick","description":"This example shows an interactive canvas visualization of 5,000 colored grid cells, where users can adjust the number of cells via a text input and hover to see a tooltip with the cell’s value. It uses D3 v4 for data binding and scales, while rendering both a visible canvas and a hidden canvas for color-based picking—mapping each cell to a unique RGB color via `getImageData` to identify hovered elements. The demo includes a timer-driven animation that redraws the grid over 300 milliseconds.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/de8f9d9c58b04b51ab3809751f1c7e2c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
