{"version":"1.0","type":"rich","title":"Letter Count Bar Chart","description":"This example demonstrates a bar chart that visualizes the frequency of each letter in a text excerpt from the Peter Piper nursery rhyme. It asynchronously loads the text file via `d3.text`, counts letters using JavaScript `Map` objects, and renders the chart with SVG rectangles. The visualization uses D3 v5 scales (`scaleLinear`, `scaleBand`) and axes (`axisBottom`, `axisRight`) to map counts to bar heights, with interactive updates triggered by `keyup` events on a textarea.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c31dc3533020482bae433ac86bf231df?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
