This interactive map visualization lets users explore world countries and Australian states through a React-based interface. The main view renders world map data from the world-atlas TopoJSON dataset using D3 projections, with controls to switch between Natural Earth, Orthographic, Mercator, and Albers projections, plus a toggle for graticule grid lines. Clicking a country displays a detail panel with population, GDP, and regional information from the GeoJSON properties. The code leverages D3's geoPath, geoGraticule, and projection functions, while an additional choropleth view colors Australian states by population using d3.scaleSequential with an interpolateBlues color scheme.

World Map

This interactive geographic visualization presents a world map and a separate map of Australia, allowing users to switch between the two views. The map supports multiple projections—including Natural Earth, Orthographic, Mercator, and Albers—and lets users toggle graticule grid lines. Clicking a country or Australian state displays a details panel with population, GDP, and continent information for world countries. The visualization is built with React and D3 v7, using `d3.geoPath` for rendering, TopoJSON data from the world-atlas package for the world map, and an external Australia states TopoJSON file, all drawn as SVG elements.

World Map and Australian States

This interactive web application presents two geographic visualizations: a world map and a map of Australian states. Using D3.js version 7 and the TopoJSON library, the application loads GeoJSON data from remote URLs, projects it via `d3.geoConicEqualArea` and `d3.geoNaturalEarth1`, and renders the maps as SVG paths. The Australian map colors each state and displays its name as a tooltip on hover, while the world map uses uniform gray fills with darker strokes for country boundaries.

Country Map

This example displays a map of Australia’s administrative regions, with each state filled in red and labeled with its name. The visualization loads GeoJSON data from `australia.json` and projects it using `d3.geoMercator` with a custom translation and scale. It uses `d3.geoPath` to generate SVG paths for the regions and `topojson.feature` to extract the geometry. State names are positioned at each region’s centroid using `d3.geoPath.centroid`, rendered as SVG text elements with a small font size.

World Map

This interactive visualization displays a world map using D3 and React, rendering Earth’s landmasses in green with country borders and graticule lines overlaid on a light gray sphere. The map is drawn using `d3.geoNaturalEarth1` projection and `d3.geoPath`, with geographic data sourced from the world-atlas TopoJSON file (countries-50m.json). Country interiors and borders are derived via `topojson.feature` and `topojson.mesh`, while React manages the SVG rendering and loading state.

World Map

This visualization presents a world map using D3's geoNaturalEarth1 projection, rendering landmasses in teal with country borders highlighted and graticules overlaid on a light gray sphere. The data comes from the World Atlas TopoJSON dataset (countries-50m.json), processed with topojson’s feature and mesh functions. React manages the SVG output, while D3’s geoPath and geoGraticule construct the geometric paths. The map emphasizes clean, minimalist styling with muted colors, illustrating global geography through a responsive, interactive-free interface.

World Map

This interactive world map uses a natural Earth projection to display global landmasses, countries, and graticule lines. The visualization renders geographic features using d3.geoPath and geoNaturalEarth1, with data sourced from the world-atlas package. Land areas appear in teal, the sphere background in light gray, and country interiors are outlined with a distinct stroke. The example demonstrates how to combine React, D3, and TopoJSON to create a stylized SVG world map.

World Map

This interactive world map visualizes the Earth’s countries using a natural Earth projection, displaying the globe’s sphere, graticules, and landmasses with custom styling. Built with React and D3 v6, the visualization loads TopoJSON data from the `world-atlas` package and processes it using `topojson`'s `feature` and `mesh` APIs to extract country boundaries and interiors. The `d3.geoNaturalEarth1` projection and `d3.geoPath` render all geographic elements as SVG paths, while CSS classes define teal and gray color schemes for a polished aesthetic.

World Map

This map uses D3.js geo utilities (geoEqualEarth, geoPath, geoGraticule) within a React component to render country borders from the World Atlas TopoJSON. The SVG view shows landmasses in cyan, ocean in gray, and a graticule for reference. The code projects sphere geometry, graticules, and TopoJSON features, with interiors drawn as stroked paths, creating a polished geographic visualization.
