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.

Fork of GeoVisualization - Choropleth map of the world

This visualization presents an orthographic choropleth map of the world, coloring each country by its population using a threshold scale with sequential blue shades. The code loads GeoJSON country boundaries and CSV population data via `d3.json` and `d3.csv`, projecting them with `d3.geoOrthographic` and rendering paths through `d3.geoPath`. Hover interactions trigger opacity transitions and stroke highlights on the SVG countries, while all elements are drawn with D3 v6 in a React environment.

Fork of GeoVisualization - Choropleth map of the world

This choropleth map of the world visualizes population by country using a threshold color scale, with dark blue representing higher populations. The map renders in SVG and responds to mouse-over and mouse-leave events by adjusting the opacity of all countries and highlighting the hovered one with a black stroke. The code loads GeoJSON boundaries and CSV population data via `Promise.all`, projects the paths using `d3.geoPath` with a Mercator projection, and colors each country through `d3.scaleThreshold` and `d3.schemeBlues`. Interactions are handled with D3 transitions for smooth visual feedback.

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 displays a choropleth map of the world, rendering country boundaries as gray paths on an SVG. When the user hovers over a country, its fill changes to red, and it reverts to gray on mouseout. The code loads GeoJSON data from a GitHub repository using `d3.json` and applies the `d3.geoEqualEarth` projection with `projection.fitExtent` to fit the map to the viewport. It uses `d3.geoPath` to generate the path data for each feature, with the SVG sized dynamically based on the window dimensions.

Fork of World Map Visualization

This visualization displays a choropleth world map colored by population data from a CSV file, with countries lacking data rendered in red. Using d3.geoNaturalEarth1 projection and d3.geoPath, it draws SVG paths from Natural Earth GeoJSON data. The d3.scaleQuantize with d3.schemeBlues applies a blue color scale to population values loaded via d3.csv, demonstrating D3 v6 with React integration.

This visualization shows a world map with countries colored by population using a threshold scale, rendered as SVG paths via `d3.geoPath` with a Mercator projection. The choropleth uses a quantized color range from light to dark blue, and hover interactions trigger tooltips built with `d3-tip`, displaying each country’s name and population. Data comes from a TopoJSON file and a TSV of population figures, both loaded asynchronously with the queue library.

This choropleth map visualizes global population by country, using a blue sequential color scale where darker shades represent higher population counts and gray indicates missing data. The visualization loads a GeoJSON world map and a CSV of population figures, then joins them by ISO3 country codes. Built with D3 v7, it uses the `geoNaturalEarth1` projection and `geoPath` to render SVG paths, with interactive tooltips showing each country’s name and population via the `append('title')` method.

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.
