This example shows an interactive map of New York cities and towns that zooms into a selected region on click, highlighting the active area in sky blue while fading other boundaries. Built with D3 v3, it uses `d3.geo.albersUsa` for projection, `d3.geo.path` for rendering TopoJSON features, and a `g.transition` with scaling and translation to animate the view. State and town borders are drawn as SVG paths, with click handling on both the background and individual regions to toggle zoom.

This example shows an interactive map of New York City boroughs, where each borough’s fill color represents the length of its name. Users can hover over or click individual boroughs to trigger visual feedback. The map is rendered using D3 v3 with `d3.json` to load GeoJSON data, `d3.geo.path` for projecting and drawing the borough outlines, and `d3.scale` for mapping name lengths to colors. The code sets up mouseover, mouseout, and click event handlers for each path.

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.

This example displays a map of New York State, rendering its geographic boundaries as steel-blue shapes on an SVG canvas. It loads GeoJSON data from a remote GitHub gist using `d3.json` and projects the coordinates with `d3.geoAlbersUsa`. The code uses `d3.geo.path()` to convert the projected features into SVG path data, appending each region as a `<path>` element within grouped `<g>` elements. The visualization relies on D3 v5 and React, with the final output showing a simple, unadorned state outline.

This example displays a map of New York counties using an Albers USA projection with D3 v3 and TopoJSON, showing county boundaries and state borders in white. Clicking a county triggers a smooth zoom animation that centers the view on that region, highlighting it in sky blue while scaling stroke widths inversely. The visualization uses `d3.geo.albersUsa`, `d3.geo.path`, and a 750-millisecond transition with the `scale` and `translate` transforms, with data loaded from a GitHub-hosted TopoJSON file.

This interactive map displays the towns of New York State, rendered as SVG paths using TopoJSON data. Users can click any town to zoom in on it with a smooth transition, and clicking again returns to the full state view. The visualization uses `d3.geo.albersUsa` for the projection and `d3.geo.path` for drawing, with click handling that triggers a 750-millisecond `g.transition` to scale and translate the view. The active town is highlighted in sky blue via CSS class toggling, while county borders remain white.

This interactive choropleth map displays a wide range of socioeconomic indicators for city neighborhoods, selectable via a dropdown menu. Built with React and D3.js, it renders neighborhood polygons as SVG paths, with colors encoding the chosen variable. A tooltip reveals the neighborhood name and its exact value on hover. A checkbox toggles the inclusion of the downtown area. The map data is visualized from a linked dataset, allowing for dynamic exploration of employment, education, and business statistics.
