This interactive choropleth map visualizes global population by country, with each nation color-coded according to population size using a threshold scale and a blue sequential color palette. Hovering over a country highlights its borders and displays a tooltip showing the country name and exact population figure. The visualization loads geographic data from a TopoJSON file and population statistics from a TSV file, then renders the map using `d3.geoMercator` projection and `d3.geoPath`. Tooltips are implemented with the d3-tip library, while the queue library manages asynchronous data loading.

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.

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.

This choropleth displays global population estimates, with each country filled using a dark red gradient that intensifies for higher population counts. The visualization loads country borders and demographic data from the world-atlas TopoJSON and TSV files, then renders them as SVG paths via d3.geoPath with a Mercator projection. Interactive zooming is enabled through d3.zoom, and hovering over a country turns it purple while a tooltip reveals its name.

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.

Fork of map exemple

This visualization displays a choropleth map of world population estimates, using darker reds to represent higher population counts. It employs d3.geoMercator and d3.geoPath to project and render country boundaries from the world-atlas TopoJSON dataset, with d3.scaleLinear mapping population estimates to fill colors. The map supports zooming via d3.zoom, and hover effects change country fills to purple. Population data is loaded from a TSV file and matched to country features by ISO numeric codes.

Fork of map exemple

This choropleth map visualizes world population estimates for each country, with a color scale ranging from light red to dark red. The map renders geographic boundaries using `d3.geoPath` with a Mercator projection, and supports zooming via `d3.zoom`. Population data comes from a TSV file and country shapes from TopoJSON, both sourced from the world-atlas package. Countries display hover effects through CSS, changing fill color to purple, and show country names via SVG `title` elements.

Fork of map exemple

This visualization displays a choropleth map of world countries, with each nation filled by a dark red color scale based on its estimated population. The map uses d3.geoMercator projection and d3.geoPath to render geographic features from the World Atlas TopoJSON data. Population values are loaded as TSV data with d3.tsv, while event handling and zoom functionality come from d3.zoom. Country labels and population estimates are attached as SVG title elements, and hover effects are styled through CSS.

This example displays a choropleth world map where each country is colored according to its population estimate, ranging from red to dark maroon. The visualization uses d3.geoMercator for projection, d3.geoPath for rendering SVG paths, and topojson.feature to convert TopoJSON data from the World Atlas 50m dataset. Population values are loaded from a TSV file and mapped to colors via d3.scaleLinear. Hovering highlights countries in purple, and d3.zoom enables pan and zoom interactions.
