{"version":"1.0","type":"rich","title":"Unhealthy AQI for SO2 in Texas","description":"A bar chart shows the count of days in Texas falling into four AQI categories for sulfur dioxide, from Good to Unhealthy. The chart is built with D3 v5, using `d3.scaleBand` and `d3.scaleLinear` for axes, and SVG elements for rendering. Hovering over a bar dims other values, highlights the selected bar, draws a dashed threshold line via a dynamically appended `line`, and displays the numeric difference between each category and the hovered one.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8adc40761ea3408a83a257f74ef2a22f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
