This choropleth map visualizes global population density by coloring each country according to its estimated population (pop_est) using a viridis sequential color scale. The map renders world geography as SVG paths via d3.geoPath, with country boundaries stroked in white and a hover effect darkening each region. The code loads world-atlas TopoJSON data through d3.json, converts it to GeoJSON with topojson.feature, and maps population values to fill colors. D3 v7 handles the SVG generation and data binding, while the color scale uses d3.scaleSequential with d3.interpolateViridis for continuous color encoding.

world map

This choropleth map visualizes global population density, with each country colored on a blue sequential scale, from light shades for lower values to darker blues for higher densities. Countries without data appear in gray. The visualization uses D3.js v7 to load TopoJSON world map data and a CSV file, converting them to GeoJSON features. The map is rendered as SVG paths using a Natural Earth projection, with an interactive tooltip on hover and a linear gradient legend showing the density range.

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.

Population Density

This choropleth map visualizes global population density across selectable years (1980, 2000, 2010, 2022) using a Mercator projection via `d3.geoMercator` and `d3.geoPath`. A threshold color scale maps density values to a blue sequential palette, with country-level data loaded from a raw GitHub CSV. Users interact through a dropdown to switch years, triggering map redraws and an animated tooltip on hover showing country name and density. A sidebar ranks the top ten most densely populated countries for the chosen year.

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.

world population density

This visualization displays world population density on a choropleth map, with a sidebar dropdown to select data from 1980, 2000, 2010, or 2022 and a table ranking the top ten most densely populated countries. It uses D3 v6 (d3.geoPath, d3.geoMercator, scaleThreshold) to render an SVG map from GeoJSON data, updating country fill colors on selection. A hover tooltip shows the country name and density value. Population density data comes from a CSV file linking country codes to values per year.

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.

world map

This world map visualizes population density across countries, with each nation colored on a sequential blue scale from light to dark based on its density value. The map renders in SVG using a Natural Earth projection via d3.geoNaturalEarth1 and d3.geoPath. It loads TopoJSON country boundaries from world-atlas and joins CSV population data by country ID, while a gradient legend shows the density range. Interactive hover tooltips display the country ID and its population density or “No data” when unavailable.

Map

This visualization is a world population density map where each country is colored according to its inhabitants per square kilometer, using a sequential color scale from light blue (sparse) to red (dense). It displays a legend and tooltips on hover, allowing users to inspect individual countries. Built with D3 v7, the map uses `d3.geoNaturalEarth1` and `d3.geoPath` to render geographic boundaries from TopoJSON data, while population statistics are parsed from a TSV file and aggregated with `d3.rollup` and `d3.sum`.
