{"version":"1.0","type":"rich","title":"D3 Starter_EP","description":"This example demonstrates a React and D3.js bar chart visualizing the frequency of letters in a small CSV dataset. The chart displays each letter on the x-axis with its corresponding count on the y-axis, featuring interactive bars that change color and opacity when clicked to highlight a selected letter. Built with React 19 and D3 v7, the application uses a custom `useDimensions` hook with ResizeObserver for responsive sizing, `d3.scaleBand` and `d3.scaleLinear` for scales, `d3.axisBottom` and `d3.axisLeft` for axes with gridlines, and `d3.csv` for data loading. The code leverages D3's selection `join` method for declarative SVG rendering within the React component lifecycle.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8acc841bb8184deda4a21db442e0bab9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
