This interactive scatter plot visualizes monthly air quality measurements for London from January 2010 through August 2018, sourced from the Kings College London Air Quality Dataset. Users select which two pollutants to plot against each other using dropdown menus, while the color of each circle encodes the month of the year using a D3 `scaleOrdinal` color scale based on `interpolateInferno`. Clicking a legend item highlights all data points from that month, dimming others. The visualization uses D3 v5, rendering as an SVG with animated transitions of 1500 milliseconds via `transition.duration` and `.delay`, with axis and legend components built using D3’s `axisBottom`, `axisLeft`, and custom `dropdownMenu` and `colorLegend` modules.

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.

Scatter plot with Menus -by Month

This interactive scatter plot visualizes London air quality data from January 2010 through August 2018, showing monthly measurements of various pollutants. Users can choose which two air quality variables to compare using dropdown menus, while data points are color-coded by month using D3's `scaleOrdinal` with the `interpolateViridis` palette. A clickable color legend filters the displayed data, and D3 transitions animate the scatter plot when the selected axes change. The visualization uses D3 v5 with SVG rendering, scaled axes, and custom axis labels to present the Kings College London Air Quality Dataset.

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.

Scatter Plot Roadside Pollution over Time

This interactive scatter plot visualizes monthly roadside pollution levels in London from January 2010 through August 2018, sourced from the Kings College London Air Quality Dataset. Each circle represents a monthly average, colored by pollutant type, with a legend that filters data on click. The visualization includes animated transitions using `transition().duration()` and `delay()`, a dropdown menu for selecting variables, and D3 v5 APIs including `scaleTime`, `scaleLinear`, `axisBottom`, and `axisLeft`. The chart renders as an SVG with interactive color legend and axis labels.

Scatter plot with Menus - by Year

This interactive scatter plot displays London’s monthly average air quality readings for PM2.5 and PM10 particulates, with each point colored by year. The visualization uses two dropdown menus implemented via the `dropdownMenu` function to let users switch the x- and y-axis variables among eight roadside and background pollutant metrics. Built with D3 v5, the chart renders SVG circles, uses `scaleLinear` for axes, `scaleOrdinal` with `schemeSpectral` for the year-based color scale, and supports a clickable color legend that highlights data points from a selected year.

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.

Fork of London Air

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.

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.
