This example shows a world choropleth map of birth rates across countries, with color intensity reflecting the rate value and gray indicating missing data. The visualization uses an SVG rendered with D3.js and React, projecting geographic features via `d3.geoMercator` and drawing them with `d3.geoPath`. Birth rate data is loaded from a CSV and matched to country names, then mapped to a sequential color scale (`d3.interpolateYlOrRd`). Hovering over a country reveals a tooltip with the specific birth rate.

Fork of Chloropleth

This visualization combines a choropleth map of global birth rates with a scatter plot of fertility rate versus life expectancy, colored by continent with point size encoding population. Hovering highlights a country in red across both views. It uses d3.geoEqualEarth, d3.geoPath, d3.scaleLinear, and d3.scaleOrdinal, with data from a world GeoJSON, a 2023 country statistics CSV, and a country-to-continent JSON. Two SVG elements render the linked map and chart.

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.

Assignment 9 World Chloropleth Map

This example presents a world choropleth map visualizing crude death rates per 1000 population in 2012, with countries colored using a threshold scale and green color scheme. A legend and title clarify the metric, while interactive tooltips display each country’s exact value on mouseover. Built with D3 v6, it uses d3.csv to load UN data, d3.json with topojson to fetch world country geometries, and d3.geoPath with a geoAlbers projection to render SVG paths. A d3.legendColor component generates the color legend.

A9 World Map in D3

This D3.js world map visualization displays the population density of countries using a blue color scale on a Natural Earth projection. The SVG-based choropleth map retrieves country boundary data from a Natural Earth GeoJSON file, while population statistics come from the CSV dataset loaded with `d3.csv`. The code uses `d3.geoPath` with `d3.geoNaturalEarth1` projection to render country shapes, and maps each country's population density value to the color scale, with gray indicating missing data. Hovering over a country reveals its name and density value through the SVG `title` element. The implementation includes `d3.scaleSequential` and `d3.interpolateBlues` for the color gradient.

Fork of Fork of Chloropleth

This example displays a choropleth map of the world, coloring countries based on their "Birth Rate" from a 2023 world-data CSV. A blue-to-red linear color scale encodes the data range, with grey indicating missing countries. The visualization renders two separate SVG canvases side-by-side, each showing the same map. The code loads GeoJSON map data, country statistics, and continent data using `Promise.all` and `d3.json`, `d3.csv`, then draws the map with `d3.geoEqualEarth` and `d3.geoPath`.

Testing around with Chloropleth

This visualization combines a choropleth map with a scatter plot to explore global demographic data. A world map displays countries colored by birth rate, while the adjacent scatter plot shows fertility rate against life expectancy, with population mapped to circle size. The map and scatter plot are linked: hovering over a country in either view highlights the corresponding element in the other. Built with React and D3 v6, the map uses `d3.geoEqualEarth` projection with `d3.geoPath`, while both views rely on `d3.scaleLinear` and `d3.scaleOrdinal` for color and size encoding.

A9 World Choropleth Map

A9 World Choropleth Map visualizes GDP per capita across countries in 2022 using a Mercator projection and a threshold color scale from `d3.scaleThreshold` and `d3.schemeBlues`. The map, rendered as SVG, colors each country path via `d3.geoPath`, with gray for missing data, and includes interactive tooltips showing country name and GDP value on mouseover. A separate SVG legend, built with `d3.legendColor`, displays the color thresholds. The code loads GeoJSON country boundaries and CSV economic data using `d3.json` and `d3.csv` with a queued `d3.queue`.

World Map Visualization

This example displays a choropleth world map where countries are colored by population using a blue sequential color scale. The visualization loads geographic boundaries from Natural Earth GeoJSON and joins them with population data from a CSV file. It leverages D3 v6 APIs including `d3.csv`, `d3.json`, `d3.geoNaturalEarth1`, `d3.geoPath`, and `d3.scaleQuantize` with `d3.schemeBlues`. Countries without matching data appear black, while the SVG rendering uses a 800x500 viewport.
