{"version":"1.0","type":"rich","title":"London Air","description":"This visualization displays monthly air quality measurements in London from January 2010 through August 2018, sourced from the Kings College London Air Quality Dataset. Users can change the pollutant displayed via a dropdown menu, and interact with two legends to filter data by month or by measurement type (Roadside or Background). The scatter plot uses time-series animation to draw the data points, with color encoding for the month and stroke encoding for the location type. The D3.js code (v5) uses `d3.csv`, `d3.scaleOrdinal`, `d3.scaleTime`, `d3.axisBottom`, `d3.axisLeft`, and `d3.transition` to build the interactive SVG visualization.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6b06a7a96b914124b70043291cd22867?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
