Forked from PM 2.5 Particle Change in US

This interactive map displays PM2.5 particle concentrations across US counties from 2000 to 2018. A slider and play button animate through yearly data, with a sequential YlGnBu color scale mapping concentration values. The visualization uses React with D3 v5’s `geoPath` and `geoIdentity` projections to render county boundaries from TopoJSON data, while county-level PM2.5 values are loaded from a CSV file. Hover tooltips reveal state and concentration details, and the color legend provides axis ticks for reference.

Fork of PM 2.5 Particle Change in US

This interactive choropleth map shows the change in PM2.5 particulate matter concentrations across US counties from 2000 to 2018. A vertical slider and play button animate through years, with counties colored on a sequential YlGnBu scale where darker blue indicates higher pollution levels. The visualization uses D3 v5 geo projections via `d3.geoIdentity` and `d3.geoPath` to render TopoJSON county boundaries from the US Atlas, with React managing the state and year updates. County-level PM2.5 data comes from a CSV file, and hover tooltips display exact values.

Fork of PM 2.5 Particle Change in US

This interactive choropleth map visualizes PM2.5 particle concentration changes across US counties from 2000 to 2018. A slider, oriented vertically on the left with auto-play, lets users scrub through the years, revealing shifting pollution hotspots. Each county polygon is filled using a `d3.scaleSequential` with `interpolateYlGnBu` color scale, where darker blues represent higher concentrations. Built with React and D3 v5, it uses `d3.geoPath` with an Albers projection on topojson data, and includes a gradient legend with tick marks for reference.

Fork of PM 2.5 Particle Change in US_test

This animated choropleth map visualizes changes in PM2.5 particle concentrations across U.S. counties from 2000 to 2018. Users can scrub through years via a vertical slider or trigger automatic playback, with color intensity reflecting pollution levels via a d3.interpolateYlGnBu sequential scale. Built with React and D3 v5, the SVG map uses d3.geoPath with a geoIdentity projection for county boundaries, while a ColorLegend component renders a gradient bar with tick marks. The data is loaded via d3.csv, and each state’s border is highlighted on hover.

PM 2.5 Particle Change in US

This interactive choropleth map visualizes annual PM2.5 particle concentrations across US counties from 2000 to 2018. A slider and play button animate through years, updating county fill colors via d3.scaleSequential with interpolateYlGnBu. The visualization uses d3.geoPath with geoIdentity projection, TopoJSON county and state boundaries, and React state management for temporal navigation. County-level data comes from a CSV file, with hover tooltips showing exact values.

Fork of Fork of new data

This interactive map shows US county-level PM2.5 air pollution concentration changes from 2000 to 2021. A vertical slider controls the year, with a play button animating through time. The map renders with d3.geoPath and geoIdentity using SVG paths, colored by a sequential YlGnBu scale. Each county path includes a tooltip displaying the state, county name, and pollution value. The visualization updates its 975×500 SVG at each year change, with data loaded from CSV files.

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.

Fork of Pollution in US with counties by React and d3

This interactive choropleth shows the concentration of PM2.5 particulate matter across US counties for each year from 2000 to 2018, with a slider and play button animating through time. County colors map to the sequential `d3.scaleSequential` with `d3.interpolateYlGnBu`, while state boundaries are drawn with `d3.geoPath` and `geoIdentity` from US Atlas TopoJSON data. React manages the year state and SVG rendering, with a D3 color legend showing the concentration scale.

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.
