{"version":"1.0","type":"rich","title":"d3 v3","description":"This visualization presents a grouped bar chart of daily air quality measurements from a single monitoring station in Phoenix, Arizona, showing mean concentrations for NO2, O3, SO2, CO, and the AQI. Built with d3.js v6, it loads data from a local CSV via `d3.csv`, parses dates with `d3.timeParse`, and uses `d3.scaleBand` for both the date and pollutant groupings. The interactive tooltip appears on mouseover, and the chart uses `d3.axisLeft` and a rotated `d3.axisBottom` with `d3.timeFormat` for clear temporal labeling.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/60be9623aca345ccae960709d79b9e5d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
