This visualization displays California counties using a conic conformal projection, with population data shown interactively on mouseover. The map initially outlines the entire United States, then focuses on California counties filled in white. The example uses d3.geoConicConformal for projection, d3.geoPath for rendering, and topojson-client to process county boundaries from a GitHub-hosted TopoJSON file. Population values come from a separate JSON dataset matched by FIPS code, displayed with d3.format. Hovering highlights counties in yellow and shows the county name with its population.

California Counties

This example visualizes California counties with a map rendered using SVG and the D3.js v4 library. It loads county boundaries from a TopoJSON file and an earthquake feed from USGS, though only the county boundaries are drawn. The map uses a conic conformal projection via `d3.geoConicConformal` and `d3.geoPath`, with the projection fit to the state’s extent. Hovering over a county highlights it in crimson and displays its name and population in an overlay, using a mouseover event and the `d3.format` API.

NY Counties

This visualization displays New York’s counties on a map, colored white with gray borders, and highlights each county in crimson on mouseover while showing its name and population in an info box. It uses d3.geoPath with a transverse Mercator projection, d3.queue to load TopoJSON county boundaries and population data, and topojson-client to convert geometries. The map also includes a blurred drop shadow and white overlay for a layered effect, with state boundaries drawn as a mesh.

NY Counties

This example visualizes earthquake epicenters overlaid on California county boundaries. Red points mark quake locations; a tooltip shows each event's magnitude and place name, while a yellow highlight appears on hover. The visualization uses a conic conformal projection and plots California counties from a TopoJSON file, with earthquake data pulled from the USGS GeoJSON feed. The code employs d3.geoPath for map rendering, d3.json for loading both datasets, and mouseover/mouseout events for interactivity.

NY Counties

This example presents a map of New York State counties, colored white with gray borders, against a backdrop of the broader U.S. boundary with a subtle drop-shadow effect. Hovering over a county highlights it in crimson and displays its name and population in an overlay. The visualization uses D3 v4 with `d3.geoPath` and a transverse Mercator projection, loading TopoJSON county geometries and population data from a GitHub repository. The map renders as SVG, leveraging a blur filter and `topojson-client` for feature conversion and state boundary meshing.

NY Counties

This example displays a map of New York counties overlaid with earthquake data from the USGS all-week feed. The visualization uses the D3.js `geoConicConformal` projection to transform geographic coordinates, with `topojson-client` converting TopoJSON to GeoJSON features for rendering as SVG paths. County boundaries appear in pink, while earthquakes are plotted as points whose color changes to yellow on mouseover, with details shown in a floating info panel. The map includes a green nation boundary with a drop-shadow effect created using SVG filters.

A map of New York counties displays population density and includes an interactive pie chart in the corner. Hovering over a county highlights it in crimson and shows its name and total population in an overlay. The visualization uses D3 v4 with `d3.geoTransverseMercator` and `d3.geoPath` to render TopoJSON county boundaries, while `d3.scaleThreshold` and `d3.schemeOrRd` color the map by density. Population data comes from a JSON file, and the pie chart is drawn with `d3.pie` and `d3.arc`.

NY Counties

A choropleth map of New York State counties colors each county by population density using a threshold scale and the d3.schemeOrRd sequential color scheme. The map uses d3.geoPath with a transverse Mercator projection, and topojson-client to convert county boundaries from TopoJSON. Hovering highlights a county and displays its name and density in a tooltip, while a legend with a power scale explains the color ranges. Data comes from a provided GeoJSON/TopoJSON and population CSV, inspired by a Mike Bostock example.

NY Counties

This example visualizes population density across New York counties using a choropleth map with a threshold scale and the OrRd color scheme. Hovering over a county highlights it and displays a small pie chart comparing population, land area, and density. The visualization is rendered with SVG and uses d3.geoPath with a Transverse Mercator projection, along with topojson-client to process county boundaries and d3.queue to load population data from JSON files.
