This example shows a choropleth-style interactive map of New York County and its surrounding counties, rendered with SVG paths. Users select a US state from a dropdown menu, which triggers an animation as the map re-centers and re-scales to fit the selected state using `d3.geoIdentity` and `d3.geoPath`. Hovering over a county highlights it in orange and displays its name in a tooltip. The visualization uses `topojson.feature` to parse US county and state boundaries from the `us-10m.v2` TopoJSON file, with data from `county_data.tsv`.

Fork of NewYorkCounty

This fork of NewYorkCounty displays a state of the US with its counties as an interactive SVG map, emphasizing a clean white and black aesthetic. The visualization's central mechanism is a dropdown selector that switches between states. Clicking on a county slides in a sidebar with its name, while hovering highlights the county in orange and shows a tooltip. It leverages d3.geoPath with a geoIdentity projection to render the map, and uses topojson-client to parse the US-10m TopoJSON file. All county and state geometry is drawn as SVG paths, with animated transitions on hover.

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.

NYS V3

An interactive choropleth map of New York State displays its counties, which change color and reveal a tooltip with the county name on hover. Clicking a county hides all others and shows a full-width “Return” button, though the code’s data-entry section is empty, so no additional details appear. Built with D3 v7 and topojson, it uses `d3.geoMercator`, `d3.geoPath`, and `d3.geoBounds` to project and render GeoJSON/TopoJSON data, with SVG paths styled via CSS.

NYS V2

This interactive map of New York State displays county boundaries, which change color on hover and can be clicked to zoom in and isolate a selected county while hiding the others. A tooltip shows the county name, and a return button restores the full map view. Built with D3 v7 and TopoJSON, it uses `d3.geoMercator`, `d3.geoPath`, and SVG elements, with county boundaries from a TopoJSON file and district data loaded from external CSV files.

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 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.

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 displays an interactive SVG map of New York State’s counties, rendered in light gray with black borders that highlight in light blue on hover. It uses D3 v3 with the Albers projection and `d3.geo.path` to draw the geographic features, filtered from a TopoJSON file by state FIPS code 36. The map loads county boundaries from a remote GitHub-hosted dataset, while an accompanying test file defines a tooltip with `d3.tip` for potential data annotations.
