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 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 4

A choropleth map of New York State counties shows population density using a threshold scale with a sequential color scheme. Hovering over a county displays a small pie chart breaking down population, land area, and density, alongside detailed statistics in an overlay. Built with D3 v4, the visualization uses `d3.geoPath` and a Transverse Mercator projection to render GeoJSON from a TopoJSON source, with `d3.scaleThreshold` and `d3.schemeOrRd` for the color encoding. A blurred drop-shadow effect is applied via SVG filters.

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

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`.

map: NY Counties

This interactive map displays New York State counties using a glitchy, layered rendering technique. The visualization uses D3’s geoAlbersUsa projection and geoPath to render county boundaries from a TopoJSON source, with hover effects that highlight individual counties. The map also includes world landmasses and graticules, creating an overlapping collage effect where the state’s counties appear superimposed on global geography. React manages the component state while D3’s json and topojson.feature APIs load and parse the geographic data for SVG rendering. The stylized CSS uses semi-transparent fills and hover states to emphasize the experimental aesthetic.

Untitled

This example visualizes the counties of New York State using a Transverse Mercator projection, with state boundaries outlined and counties filled in gray. Hovering over a county highlights it in light blue. The code loads US TopoJSON data via `d3.json`, extracts New York using `topojson.feature`, and applies a clipping path to restrict county paths to the state outline. It uses `d3.geo.path` for rendering and `path.bounds` to auto-fit the projection scale and translation.

NY state map

A choropleth-style SVG map displays New York State's counties, filtered from a TopoJSON US atlas by state FIPS code. The map uses the Albers USA projection via `d3.geoAlbersUsa()` and renders county boundaries with `d3.geoPath()`. D3's data join methods add, update, and remove path elements as data changes. County shapes are filled pale green with gray strokes, sized within an 800 by 900 pixel SVG.

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.
