{"version":"1.0","type":"rich","title":"Bar Chart with Tooltip with Tooltip D3 V4","description":"This bar chart displays average house prices for regional and national areas, using two purple-and-pink bars on a light background. It loads JSON data via `d3.json`, encodes the x-axis with `d3.scaleBand` and the y-axis with `d3.scaleLinear`, and formats y-axis ticks as thousands with \"K\". A custom tooltip div appears on `mousemove`, showing the area name and price, and disappears on `mouseout`. The chart uses conventional margins, `d3.axisBottom` and `d3.axisLeft`, and renders in SVG.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-274bf248fd0f362d64674920e85c1eb7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
