{"version":"1.0","type":"rich","title":"Diverging Bar Chart","description":"This diverging bar chart visualizes the percentage by which water quality measurements at three sample points exceed regulatory limits. Data is loaded from a CSV and grouped by pollutant parameter, with the average exceedance calculated for each category. Bars are rendered horizontally along a linear percent scale, extending to the right when the average exceeds the limit. A categorical y-axis orders parameters by descending exceedance, and an interactive tooltip provides additional detail. The chart uses an SVG layout with D3 v4 and includes a subtle animation when bars are drawn.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-9f3fde0a569cb50d54ab531b59255e81?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
