This choropleth map displays approximate population data for select countries, with values in millions encoded through a sequential blue color scale. Countries without data appear in gray. The visualization uses d3.geoNaturalEarth1 for projection, d3.geoPath for rendering geographic features from TopoJSON data, and d3.scaleSequential with d3.interpolateBlues for color mapping. Interactive tooltips appear on mouse movement, showing each country’s name and population value. A simple legend accompanies the SVG rendering.

ICE 8 making map

This choropleth map shows global population by country in 2022, with darker blue shading indicating higher population counts. The visualization uses d3.geoNaturalEarth1 for the map projection and d3.geoPath to render country outlines from TopoJSON data loaded via the world-atlas package. Population values are joined to country geometries using CSV data from a GitHub repository, with missing countries shown in gray. A sequential square-root color scale (d3.scaleSequentialSqrt) maps population values to the interpolateBlues color scheme, and hovering reveals a tooltip with the exact population via appended `<title>` elements.

ICE 8 making map

This choropleth map shows estimated country populations for 2023, with darker blue-green shades representing higher population counts and gray indicating missing data. It uses a Natural Earth projection via `d3.geoNaturalEarth1` and renders country boundaries with `d3.geoPath` from TopoJSON data loaded with `d3.json`. Population values from a CSV file are mapped to a sequential color scale, and hover tooltips display each country’s name and population. A gradient legend with a linear scale shows the population range, all rendered as SVG using d3.v7.

ICE 8 TASK 1.1

This choropleth map uses a Natural Earth projection to visualize population data for 20 countries, with darker blue shades representing higher values. The visualization loads world geometries from the world-atlas TopoJSON dataset via `d3.json` and merges CSV population data using a lookup dictionary. Countries are rendered as SVG paths using `d3.geoPath`, with missing data shown in light gray. A sequential blue color scale (`d3.scaleSequential`) and gradient legend communicate the population range, while a tooltip displays exact values on hover.

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.

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.

ICE 8

A world choropleth built with D3 v7 and React renders population figures from a CSV of 2023 estimates onto an Equirectangular projection using `d3.geoPath` and topojson country boundaries. A sequential blue color scale encodes each nation’s population in millions, with gray for missing data. Hovering a country reveals a tooltip with its name and population value, while name aliases reconcile common CSV labels to the topojson’s official names.

ICE 8 - 1

This visualization displays a choropleth world map highlighting population distribution across selected countries using a red sequential color scale. The SVG-based map uses the Mercator projection via `d3.geoMercator` and renders country boundaries from TopoJSON world-atlas data with `d3.geoPath`. Population values for five nations, including India and China, are mapped through `d3.scaleSequential` with `d3.interpolateReds`; countries without data appear gray.

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.
