A choropleth map of the United States displays PM2.5 concentration levels for counties in the year 2000, using a sequential YlGnBu color scale from d3.interpolateYlGnBu. County boundaries come from the US Atlas TopoJSON file, rendered as SVG paths via d3.geoPath and geoIdentity. A linear gradient legend annotates the concentration scale. Data is loaded from a CSV using d3.csv and filtered into a Map for lookup. The visualization is built with React and D3 v5.

Pollution in US with counties with color legend

This visualization displays PM2.5 concentration levels for US counties in the year 2000, with each county colored according to its pollution level. Counties without data appear in grey, while the color legend uses d3.interpolateYlGnBu to map concentration values. The map uses d3.geoPath with a geoIdentity projection fitted to US county boundary data from the US Atlas TopoJSON. The React-based implementation loads CSV data containing PM2.5 measurements and creates a Map for lookups, encoding values through a d3.scaleSequential color scale.

Pollution in US with counties by React and d3

This choropleth map displays PM2.5 air pollution concentrations across US counties for the year 2000, with counties lacking data rendered in grey. Built with React and d3.v5, the visualization uses `d3.geoIdentity` and `d3.geoPath` to project county boundaries from a TopoJSON atlas, while a `d3.scaleSequential` with an `interpolateYlGnBu` color scheme encodes pollution values. The data originates from a CSV file of county-level PM2.5 measurements, filtered through a custom React hook and passed as a Map to the SVG marks component.

Pollution in US with counties by React and d3

This interactive choropleth visualizes PM2.5 pollution levels across US counties from 2000 to 2018. Users can drag a vertical slider or press a play button to animate through years, with county colors transitioning smoothly via the sequential `d3.interpolateYlGnBu` scale. Built with React and D3 v5, it uses `d3.geoPath` and `geoIdentity` projection to render county boundaries from the US Atlas TopoJSON, while county pollution data is loaded from a CSV and mapped to each feature. The legend displays the concentration range, and hovering over a county reveals its name and value.

Fork of Pollution in US with counties by React and d3

This choropleth map shows the concentration of PM2.5 air pollution across US counties from 2000 to 2018, with an animated play button and slider enabling temporal exploration. County colors encode pollution levels using a sequential YlGnBu scale, while state boundaries highlight administrative context. The visualization is built with React and D3 v5, using `geoPath` with `geoIdentity` projection to render SVG county shapes from US Atlas TopoJSON, with data from a CSV of county-level PM2.5 measurements.

Two Decades of Pollution in US

This visualization shows PM2.5 pollution across US counties for the year 2000, using a choropleth map colored by concentration levels. It builds the map with vega-lite-api, joining county GeoJSON topojson data with a PM2.5 CSV dataset via a lookup transform. The visualization uses an Albers USA projection, encodes the pollution values on a clamped color scale, and renders tooltips showing exact concentrations. It integrates D3 version 5 and React for the interface setup.

PM2.5 in US

A choropleth map of the United States displays county-level PM2.5 concentration for each year from 2000 to 2018, using a yellow-to-blue color scale to indicate air pollution levels. An interactive vertical slider and a play button animate through the years. Built with React and D3, it uses `d3.geoPath` for the map, `d3.interpolateRdYlBu` for the color gradient, and TopoJSON for state and county boundaries. Data comes from county PM2.5 measurements, with missing areas in grey.

Fork of Pollution in US with counties by React and d3

This choropleth visualizes PM2.5 air pollution concentrations across US counties from 2000 to 2018, with a slider and play button animating through years. County colors map to concentration values via a quantile scale, while county and state boundaries are rendered using d3.geoPath with TopoJSON data from the US Atlas. React manages the interactive year state, and d3 provides the color interpolation and legend scales. Hovering reveals county names and exact values through SVG titles.

Fork of Pollution in US with counties by React and d3

This choropleth map of US counties visualizes PM2.5 concentration per year from 2000 to 2018, allowing users to select a specific year or trigger a play animation that cycles through the data. The map colors each county using a sequential YlGnBu color scale via `d3.scaleSequential` and `d3.interpolateYlGnBu`, with grey indicating missing data. The map is rendered with `d3.geoPath` and a `geoIdentity` projection, while a slider and play button control the temporal dimension. Data comes from a CSV file of county-level PM2.5 values, and county boundaries from the US Atlas TopoJSON.
