This choropleth map visualizes global population data using a Mercator projection and color-encoded country values. D3 v7 loads GeoJSON world boundaries and CSV population data via `Promise.all`, then applies a sequential `d3.scaleSequential` with an `interpolateYlGnBu` color scheme. The code uses `d3.geoPath` and `d3.geoMercator` to render SVG paths, and displays a linear gradient legend with an axis. Countries lacking population data render in gray, while hover tooltips provide country names and values.

ICE-8 – World Map

This visualization displays a world map where each country is colored according to its population, using a sequential blue scale to encode population magnitude. Country areas without matching data appear gray. The map uses an equirectangular projection with `d3.geoPath`, drawing country boundaries from TopoJSON data from the world-atlas package. Population values from a CSV file are joined to country names, and the color scale uses `d3.scaleSequential` with `d3.interpolateBlues`. A continuous color legend is rendered using Canvas and `d3.axisBottom` for context.

ICE-8 — World Map (Population)

This choropleth map shows global population by country, with each nation colored on a blue sequential scale based on its total population. The visualization joins World Geojson map features with population data from a CSV file using their shared ISO-3 country codes, rendering countries with missing data in gray. Built with D3 v7, it uses d3.geoPath with an equirectangular projection and d3.scaleSequential for color encoding, while interactive tooltips reveal country names and formatted population values on hover.

ICE8-world-map

This world map visualizes population values for 20 countries using a sequential blue color scale, with lighter shades for smaller populations and darker shades for larger ones. Hovering over a country displays a tooltip with its name and population. The visualization uses d3.geoNaturalEarth1 for projection, d3.geoPath for rendering SVG paths from TopoJSON data, and d3.scaleSequential with d3.interpolateBlues for coloring. Population data comes from a local CSV file, while country boundaries load from the world-atlas TopoJSON collection.

ICE8

This interactive world map visualizes country populations with a sequential YlGnBu color scale. It loads TopoJSON world boundaries via `d3.json` and population data from a CSV, then joins them through ISO country codes. The SVG map uses `d3.geoNaturalEarth1` and `d3.geoPath` to render countries, with hover tooltips and an axis-labeled gradient legend built using `d3.scaleSequential` and `d3.axisBottom`. Missing values are shown in gray.

ICE8_WorldMap

This example displays a world map with countries colored by population estimates, using a green fill that darkens on hover and supports interactive zooming. Built with D3 v5 and the topojson library, it loads geographic data from the world-atlas package and renders paths via `d3.geoPath` with a Mercator projection. The visualization applies a linear color scale based on population values from a TSV data file, and includes zoom functionality through D3’s `d3.zoom` module.

ICE-8 World Map.

This choropleth map visualizes the world’s ten most populous countries by filling each nation with a color from a sequential YlGnBu scale. Population values, hard-coded in the page or loaded from a CSV, drive the color intensity, with other countries appearing in a neutral cream. The map is rendered using `d3.geoPath` with a Natural Earth projection, transforming geospatial data from TopoJSON into SVG paths. Tooltips show each nation’s exact population. The example uses D3 v7 and the `topojson` library for feature conversion.

ICE 8 making map

A world map shades each country according to its latest reported population, using a yellow-orange-red sequential color scale; countries without data appear gray. Hovering reveals a tooltip with the country name and its population. The visualization loads a world TopoJSON atlas and a population CSV, then projects the GeoJSON features with `d3.geoNaturalEarth1` and draws them as SVG paths via `d3.geoPath`. A linear gradient legend with axis ticks shows the population range.

ICE-8 map mapping

A world map uses a natural Earth projection to visualize population data by country, with a sequential grey color scale mapping each nation’s population value from a CSV file. Built with d3.geoNaturalEarth1, d3.geoPath, and d3.geoGraticule, the SVG renders countries as colored paths with tooltips showing names and counts, plus a gradient legend. The visualization highlights shared borders using topojson.mesh, and countries lacking data appear in a neutral gray.
