{"version":"1.0","type":"rich","title":"Letter Count Bar Chart","description":"This interactive bar chart displays the frequency of each letter in the text of the “Peter Piper” nursery rhyme, loaded asynchronously via `d3.text()`. Users can edit the text in a textarea to update the counts live, with the visualization re-rendering on each keyup event. The chart uses D3 v5 scales (`d3.scaleLinear` for counts, `d3.scaleBand` for letters), SVG rectangles for bars, and axes (`d3.axisBottom`, `d3.axisRight`). Letter counting is implemented in JavaScript with a `Map` object, and updates use D3’s data join.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9fefce5b0d234b17954592f49086afc7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
