{"version":"1.0","type":"rich","title":"world map","description":"An interactive bar chart demonstrates how data updates respond to user controls. Buttons increment values, filter entries below 50, or append random numbers, while D3 transitions animate the bars and tooltips. The React component manages state with hooks, and a custom `useResizeObserver` hook dynamically recalculates scales when the container resizes. The SVG rendering uses `scaleBand` for the x-axis, `scaleLinear` for y and color scales, and `axisBottom`/`axisLeft` to draw axes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/02a613db397a487c9d609987d9bb02a4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
