This example presents a choropleth map of U.S. states, with each state filled using a color scale from light yellow to dark red based on randomly generated low, average, and high values. Hovering over a state triggers a tooltip that displays these three metrics in a table. The visualization uses D3 v3 and SVG, with the `uStates` library providing the map outlines and `d3.interpolate` for color encoding. State boundaries are drawn as paths, and the tooltip appears dynamically near the cursor.

This choropleth map of the United States displays sample data for each state, with tooltips showing low, average, and high values on hover. Built with React and D3 v3, it renders states as SVG paths using the `uStates.js` helper, and colors each state via `d3.interpolate` from a yellow-to-dark-red scale based on randomly generated data. The custom tooltip div appears on mouseover, populated by the `tooltipHtml` function.

This example displays a choropleth map of the United States, coloring each state based on a numeric diversity value ranging from 0 to 5, with values mapped to a categorical color scale from grey to dark red. The map renders state boundaries using D3’s `d3.geoPath` and TopoJSON data from the US 10m dataset, while state fill colors are assigned via an ordinal `d3.scaleOrdinal`. The code loads the TopoJSON file and appends SVG paths for each state, using the diversity object to set fill colors and adding white state borders.

This example displays a choropleth-style map of the United States using SVG paths. It renders state boundaries and fills each state as a separate path, with a hover effect that turns states red via CSS. The visualization loads TopoJSON data from a remote URL and converts it to GeoJSON using the `topojson.feature` and `topojson.mesh` APIs. It relies on `d3.geoPath` to project and draw the geographic shapes, while `d3.json` fetches the data asynchronously. State borders are drawn as a white stroke overlay for visual separation.

This example shows a choropleth map of the United States, with states colored by whether the author has lived in, visited, or never visited them. Overlaid circles mark cities where the author has resided, with circle size scaled by years spent there. Hovering a circle reveals a tooltip with the city name. The visualization is built with D3 v3, using `d3.geo.albersUsa` and `d3.geo.path` to render GeoJSON state boundaries, while a linear color scale and SVG circles encode the categorical and quantitative data.

US State Map

This interactive map of the United States uses D3 v3 to render state boundaries as SVG paths from the included `uStates.js` data file. Each state is colored according to randomly generated sample statistics—low, average, and high values—using an interpolated color scale from light yellow to dark red. Hovering over a state triggers a CSS-based tooltip that displays the state's name and its low, average, and high values in a styled HTML table. The map animates state fills on hover with a subtle opacity change, while the tooltip follows the cursor, providing a clean and informative way to explore the data.

This choropleth displays the 50 U.S. states with land areas filled in green and white state borders, highlighting a state in orange on hover. It uses React and D3 v5’s `geoPath` with the `geoAlbersUsaTerritories` projection to render geographic features as SVG, pulled from TopoJSON data in the US Atlas (`states-10m.json`). The `feature` and `mesh` functions from TopoJSON extract land polygons and interior boundaries, which are styled via CSS.

Untitled

This example displays a map of the United States with individual state boundaries rendered as SVG paths. The visualization uses TopoJSON data from the us-10m dataset, with states drawn via d3.geoPath and state borders emphasized with a white stroke. The code employs the D3 v4 library and topojson.feature to extract state geometries, while a CSS hover effect turns states red for interactive feedback. The rendering is purely SVG-based within a React framework.

This visualization displays a choropleth map of the United States, coloring each state in red with thin black internal borders. The map is rendered using React and D3 v5, with geographic shapes generated through `d3.geoAlbers` projection and `d3.geoPath`. State boundaries come from the US Atlas TopoJSON dataset, processed via `topojson.feature` and `topojson.mesh`. The SVG paths change to sky blue on hover using CSS, providing simple interactivity.
