{"version":"1.0","type":"rich","title":"Brushable bar chart of number of top-rated restaurants in GB area","description":"This brushable bar chart displays the number of top-rated restaurants across Greater Boston cities, with Boston’s count of 1,012 dominating the view. Users brush across the mini bar chart on the right to filter which cities appear in the main chart on the left. The implementation uses D3 v3 with SVG rendering, employing `d3.scale.ordinal` for bar positioning and `d3.svg.brush` to capture the brush extents. The y-axis zoom effect is achieved by mapping brush coordinates through `d3.scale.linear` to adjust the main chart’s domain. Data is loaded from a CSV containing city names and restaurant counts.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/45d0012ebcab449980c312d7b67c5b4b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
