A choropleth map shows the number of legal immigrants per country, with a threshold color scale ranging from gray to dark blue. Built with D3 v4, the visualization loads GeoJSON country boundaries and a CSV of immigration totals, then projects them using `d3.geoRobinson()` and draws paths with `d3.geoPath()`. Interactivity includes hover effects that highlight each country and display a tooltip with its name and total, plus a legend mapping color ranges to values.

Choropleth World population map

A choropleth map displays world population by country, with each nation colored on a gradient from light to dark red based on its population size. The visualization uses the Robinson projection to render the world map, and employs a color scale defined by `d3.scaleThreshold` with a sequential color scheme. The map is drawn using `d3.geoPath`, with country boundaries loaded from a GeoJSON file and population data from a CSV. An interactive tooltip appears on mouseover, showing the country name and its population.

Choropleth World population map

A choropleth world map visualizes population data by country, using sequential color intensity from a threshold color scale to represent population magnitude. The visualization employs a Robinson projection to render the geographic layout, with each country's fill color derived from a CSV dataset joined to the GeoJSON map data. Interactive features include tooltips on hover, displaying the country name and calculated population in millions, while click and hover events trigger opacity and stroke changes. The implementation utilizes d3.geoPath for map drawing, d3.scaleThreshold for color classification, and d3.queue for asynchronous data loading, all rendered as SVG elements within a styled HTML container.

Choropleth World population map

A choropleth map of the world colors each country according to its population, using a threshold color scale with a sequential red palette. Hovering over a country dims others and reveals a tooltip with the country name and population in millions, while clicking zooms the map. Population data is joined to GeoJSON country outlines via three-letter country codes, and the map is rendered as SVG using `d3.geoRobinson`, `d3.geoPath`, and `d3.scaleThreshold` with an animated `transition` on opacity and stroke.

Choropleth map

This choropleth map visualizes annual population growth rates by country for 2017, using a diverging color scale from indigo (negative growth) to white (no change) to dark green (positive growth). The visualization renders world country shapes using D3’s `geoEqualEarth` projection and `geoPath`, with graticule and sphere overlays. It loads World Bank data from a CSV and geospatial data from GeoJSON, and includes an interactive tooltip on hover plus a user-location marker via the Geolocation API.

chloropleth

This choropleth map displays global population by country, with a blue color scale indicating population ranges. Built with d3.js, it uses `d3.geoMercator` for projection and `d3.geoPath` to draw country boundaries from a GeoJSON dataset. Population data from a CSV file is matched to each country via a `Map`, and `d3.scaleThreshold` maps values to a color scheme. Hovering over a country triggers a transition that dims other countries and highlights the selected one with a black stroke.

Choropleth map

This choropleth map displays global population data by country, with a threshold color scale using `d3.scaleThreshold` and `d3.schemeBlues`. The example loads world GeoJSON topology and population CSV data via `d3.json` and `d3.csv`, rendering the map with `d3.geoPath` and a Mercator projection. Interactive buttons allow switching between music genres, though the map itself does not respond to these selections. The visualization uses D3 v4 and SVG rendering within a 400x300 viewport.

GeoVisualization - Choropleth map of the world

This example presents a choropleth map of the world, coloring each country according to its population using a threshold color scale with sequential blues. The visualization uses D3.js (v6) to load GeoJSON and CSV data, projecting the map with a Mercator projection via `d3.geoMercator` and drawing paths with `d3.geoPath`. Interactivity highlights countries on mouseover by adjusting opacity and stroke, while the SVG rendering displays the result.

Fork of GeoVisualization - Choropleth map of the world

This example shows a choropleth map of the world coloring each country by population, with a blue threshold color scale. It uses `d3.geoPath` and `d3.geoMercator` to project and draw country boundaries from a GeoJSON file, while population data is loaded from a CSV and mapped by country code. Mouseover transitions dim all countries except the hovered one, which gains a black stroke. The visualization is built with D3 v6 and rendered as SVG, using `d3.scaleThreshold` and `d3.schemeBlues[7]` for the color encoding.
