{"version":"1.0","type":"rich","title":"d3 Practice","description":"A dynamic bar chart displays a shifting dataset of 20 values, with each bar’s height and color (from black to yellow) encoding its current value. Clicking the paragraph triggers a random new value, pushing it into the array and shifting out the oldest. Using d3.v4, the code binds data to SVG `rect` and `text` elements via `d3.scaleBand`, `d3.scaleLinear`, and keyed joins, animating transitions with `transition().duration()` to slide bars leftward, update their heights, and remove exiting elements.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-049bb86bb056be437c4d76cb91022d70?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
