This interactive scatter plot visualizes monthly air quality measurements from the London Datastore (January 2010–August 2018), showing pollutant levels over time. Users can select which pollutant to display on the y-axis via a dropdown menu, while the color legend encodes the month and a second legend distinguishes Roadside versus Background measurement types. Built with D3 v5, the visualization uses `scaleOrdinal`, `scaleTime`, and `scaleLinear` for encoding, with clickable legends, animated transitions, and interactive tooltips. The color legend supports filtering by clicking, and the stroke legend uses `transition.attrTween` for updates.

In this plot I played with adding interaction to the legend, and the drop down menur for the polutant. I also added a second legend to encode wether it was a Roadside or Background measure

</n> Data in this scatter plot is from from the Kings College London Air Quality Dataset in the London Datastore. The data is from January 2010 through August 2018.

Fork of London Air

This scatter plot displays monthly London air quality measurements from January 2010 through August 2018, sourced from the Kings College London Air Quality Dataset. The visualization uses D3 v5 to render an SVG with animated transitions, where users can select pollutants via a dropdown menu and filter data points by clicking interactive legends for both month and monitoring site type. The color legend encodes months using an interpolateBuPu scale, while the stroke legend distinguishes Roadside versus Background measurements using scaleOrdinal.

London Air

This scatter plot visualizes monthly air quality measurements from the Kings College London Air Quality Dataset, showing pollutant levels over time from January 2010 through August 2018. Users select a pollutant from a dropdown menu to update the y-axis, click color-coded month and type legends to filter data points, and hover over circles to see tooltips with values. The visualization uses d3.scaleTime, d3.scaleLinear, d3.scaleOrdinal with interpolateBuPu for the color palette, and animated transitions triggered by axis updates.

London Air

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.

London Air

This visualization displays monthly air quality measurements from the Kings College London dataset, plotting pollutant concentrations over time with circles colored by year and outlined by measurement type. The chart includes interactive legends that filter data by color or stroke value, a dropdown menu to select pollutant columns, and hover tooltips showing readings. Built with D3 v5, it uses scales for color and time axes, transitions for animated updates, and separate legend components for year and measurement type.

London Air2

This visualization displays monthly air quality measurements from the Kings College London dataset, with pollutant concentrations shown over time. Users can select different pollutants via a dropdown menu, while interactive legends filter data points by year and by measurement type (Roadside or Background). The SVG scatter plot uses d3.scaleTime, d3.scaleLinear, d3.scaleOrdinal with interpolateBuPu colors, and animated transitions for circles. Tooltips appear on hover, and legend clicks trigger opacity and radius changes to emphasize selected categories.

Fork of Multiple Line plot with Dropdown

This visualization presents monthly air quality measurements for London from January 2010 through August 2018, using data from the Kings College London Air Quality Dataset in the London Datastore. A dropdown menu lets users select which pollutant to plot on the y-axis, while colored lines show annual trends for each year. Built with D3 v5, the example uses `scaleTime`, `scaleLinear`, `nest`, and `line` to generate smooth curves, with a transition animation updating the chart when the selection changes. The chart includes a color legend and axis labels.

Scatter plot with Interactive Filtering

This scatter plot displays London monthly air quality measurements from January 2010 through August 2018, sourced from the Kings College London Air Quality Dataset in the London Datastore. It plots Roadside PM2.5 particulate levels on the x-axis against Roadside PM10 levels on the y-axis, with points colored by year using a sequential color scheme. The visualization supports interactive filtering: clicking a year in the color legend dims points from other years and highlights the selected year’s data with a black outline. Built with d3.v5, the example uses `scaleLinear`, `scaleOrdinal`, `schemeRdYlBu`, `axisBottom`, `axisLeft`, and SVG rendering for both the scatter plot and legend.

Scatter Plot Pollutant (Menu) over Time

This interactive scatter plot visualizes monthly air quality in London from January 2010 through August 2018, using data from the Kings College London Air Quality Dataset. Users can select different pollutant metrics for the x- and y-axes via dropdown menus, while the color legend encodes months and allows filtering by clicking. The visualization uses D3 v5 with SVG rendering and animated transitions, employing `scaleTime` for the temporal x-axis, `scaleLinear` for pollutant measurements, and `scaleOrdinal` with `interpolateInferno` for the month color scale.
