{"version":"1.0","type":"rich","title":"Hash avatar","description":"This example renders a grid of vertical lines as a simple hash-based avatar. Each line’s stroke width and dash pattern are derived from two-bit values in a hard-coded array, using `d3.select` and `d3.selectAll` to append SVG `line` elements. The code uses bitmask operations to map each value to either a thin or bold stroke, and to solid or dashed styles, producing a compact visual identity from numeric data.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/aab3dd1a3a904b56b721d6fd286a43e9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
