D3: GeoEarth

This interactive chloropleth map visualizes global deaths from brain and central nervous system cancer in 2019, using a yellow-to-red sequential color scale via `d3.scaleSequential` and `d3.interpolateYlOrRd`. A `d3.geoNaturalEarth1` projection renders country boundaries from the World Atlas TopoJSON, with each country’s fill determined by matching ISO country codes from a CSV to cancer mortality data. Users hover over a country to display its name and total deaths in a floating tooltip, while a legend shows the color scale range. The visualization uses React for state management, `d3.geoPath` for drawing, and `topojson.feature` for geographic data processing.

D3: GeoEarth

A choropleth world map visualizes 2019 death rates from brain and central nervous system cancer by country, using an orange-to-red sequential color scale. The map is rendered with `d3.geoPath` and `d3.geoNaturalEarth1` projection, with country boundaries from World Atlas TopoJSON. React manages state for data loading via `d3.csv` and a custom hook, while hover interactions append tooltip text. A legend built with SVG rectangles shows the color scale’s domain, and the code uses `d3.scaleSequential` with `interpolateYlOrRd` for color encoding.

This example shows a world map colored by deaths from brain and central nervous system cancer for 2019, using a yellow-orange sequential color scale. It renders geographic features with `d3.geoPath` and `geoNaturalEarth1`, pulling country shapes from world-atlas TopoJSON and matching them to CSV data via country codes. A mouseover tooltip appends the country name and death count, while a legend displays the color scale’s range. The code uses React hooks to load data and D3 v7 for mapping, with the topojson library for feature extraction.

This choropleth map visualizes deaths from brain and central nervous system cancer across countries for 2019, using a yellow-to-red sequential color scale to encode mortality counts. The visualization renders world geography with `d3.geoNaturalEarth1` and `d3.geoPath`, combining TopoJSON country boundaries from the World Atlas with CSV health data joined via country codes. React manages interactive state, while D3’s `scaleSequential` with `interpolateYlOrRd` drives the color encoding. Hovering over a country displays its name and total deaths in a floating toolkit, and a legend shows the scale’s domain.

This choropleth map visualizes brain and central nervous system cancer deaths for countries in 2019, using a yellow-to-red sequential color scale from D3’s `scaleSequential` and `interpolateYlOrRd`. The map renders with `geoNaturalEarth1`, `geoPath`, and TopoJSON world-atlas data. Hovering over a country reveals its name and total deaths via a tooltip appended with D3’s `select`. React manages state and lifecycle, loading CSV data from two external sources, while a static legend at the left encodes death-count ranges.

This visualization displays global deaths from brain and central nervous system cancer for 2019, using a natural Earth projection with a sequential yellow-orange-red color scale. It shows country-level data from a CSV dataset of cancer statistics, mapped via ISO codes to world atlas geography. The code uses React to manage state, d3.geoPath and geoNaturalEarth1 for map rendering, d3.scaleSequential with interpolateYlOrRd for coloring, and topojson’s feature method to convert TopoJSON boundaries. Hovering reveals country names and death counts via a tooltip, while a legend indicates color ranges.

Fork of D3: GeoEarth

This interactive choropleth map visualizes global brain and central nervous system cancer deaths for the year 2019, colored using a yellow-to-red sequential scale. Built with React and D3 v7, it uses `d3.geoPath` and `d3.geoNaturalEarth1` for map projection, while `d3.csv` loads the data appended to a TopoJSON world atlas. A legend and hover tooltip, implemented with `d3.select`, show the total death counts per country.

This choropleth map visualizes global deaths from brain and central nervous system cancer for 2019, using a yellow-orange-red sequential color scale to encode mortality counts by country. The visualization uses React for component structure and D3 v7 APIs including `d3.geoNaturalEarth1`, `d3.geoPath`, and `d3.scaleSequential` to render the map, with TopoJSON world atlas data for country boundaries. A legend displays graduated color swatches, and hovering over a country reveals its name and total death count via D3 selections on a DOM overlay.
