{"version":"1.0","type":"rich","title":"London Air Scatter Plot Back vs Road","description":"A scatter plot visualizes London air quality measurements from 2010 to 2018, plotting monthly pollutant levels (such as PM2.5 and ozone) against time. Users can select different pollutants via dropdown menus. The color of each point represents the type of monitoring site (backstreet or roadside), and clicking a legend entry filters the visualization to that category. Tooltips show data details on hover, while axis transitions animate when new variables are selected. The visualization uses D3 v5's `scaleTime`, `scaleLinear`, and `d3.axisBottom`/`axisLeft`, with data loaded from a CSV file and rendered as SVG circles.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/880dcd1fb08d4032b36927c7d59ab434?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
