{"version":"1.0","type":"rich","title":"Color by Month Example","description":"This example uses an interactive scatter plot to show monthly air quality in London from 2010 to 2018, plotting roadside PM2.5 against PM10 particulates. A color legend allows viewers to click a month to highlight datapoints from that month while dimming others. The visualization, built with D3 v5, uses `scaleOrdinal` with an `interpolateRainbow` color scale, SVG circles for the data points, and a custom `colorLegend` module for clickable filtering. Data comes from the Kings College London Air Quality Dataset via the London Datastore.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7556874c01e843be853e965839c79e79?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
