Fork of Choropleth Map with Interactive Filtering

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.

Visualisation GES

This specimen charts the average greenhouse gas (GES) emission rate against vehicle speed, with point size reflecting carbon monoxide output and color encoding fuel consumption. It also includes tooltips for additional pollutants like NOx and PM10. The visualization is built with the vega-lite-api and d3.v5, fetching semicolon-delimited CSV data from a GitHub repository and rendering to SVG via Vega-Lite. The appearance is customized through a config file, adjusting axes, title, and font styles.
