This example displays a world population choropleth map, coloring selected countries from a custom dataset by population using a blue color scale. The visualization is built with D3 v7 and TopoJSON, projecting geographic data with `d3.geoNaturalEarth1()`. Country polygons are rendered using `d3.geoPath()`, and a hover tooltip shows the country name and population. A quantized legend created with `d3.scaleQuantize()` and `d3.axisBottom()` maps the color range to population values.

Question 1 – World Population Map

This choropleth map displays world population data for select countries, using a blue sequential color scale to encode each nation's population in millions. The visualization is built with D3.v7 and topojson-client, loading geographic boundaries from a world-atlas dataset and using a Natural Earth projection via `d3.geoNaturalEarth1`. Hovering over a country triggers a tooltip showing its name and population, with `d3.scaleSequential` and `d3.interpolateBlues` driving the color mapping.

question-1

This choropleth map visualizes world population by country using a natural Earth projection. It colors each country with a sequential YlGnBu color scale, where darker shades indicate higher population values, and provides a legend showing the population scale. The visualization uses D3's `d3.geoNaturalEarth1` projection and `d3.geoPath` to render countries from TopoJSON data, while population CSV values are mapped to each country's numeric ID. Interactive tooltips display country names and population totals on hover, built with D3 event handlers and an HTML overlay.

Ice8_Question1

This choropleth map visualizes world population by country, with countries colored according to their population values and tooltips revealing exact figures on hover. The visualization uses D3 v7's `d3.geoNaturalEarth1` projection and `d3.geoPath` to render TopoJSON world geography, while population data is joined to country shapes via a mapping between numeric IDs and ISO3 codes. A legend and interactive tooltip enhance readability of the population distribution.

Map

A world choropleth map visualizes population by country using a blue threshold color scale. The SVG rendering combines world-atlas TopoJSON geographic features with population data from a local JSON file, linked by country ID. D3's `geoNaturalEarth1` projection, `geoPath`, and `geoGraticule` draw the map and grid lines, while hover tooltips reveal country names and formatted population values.

ice 8_country

This example shows a choropleth world map of population by country, with darker blue shades indicating higher values and a gradient legend on the right. It uses d3.geoNaturalEarth1 and d3.geoPath to project and render country boundaries from a TopoJSON world-atlas dataset. Population values are loaded via d3.csv from a GitHub gist and mapped to a d3.scaleSequential with the interpolateBlues interpolator. Labels display three-letter country abbreviations, while d3.axisRight and a linearGradient define the legend.

Making Maps

This example shows a choropleth world map where a small set of countries are shaded from light blue to dark blue according to their population in millions, taken from an inline data array. It uses D3 v7, TopoJSON’s `feature` function, a `d3.scaleLinear` color scale, and `d3.geoNaturalEarth1` projection with `d3.geoPath` to render countries from the world-atlas dataset as SVG paths. The map displays tooltips with each country’s name and population or “n/a” for unlisted countries.

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`.

Q1_Ice8

This choropleth map visualizes world population data by country, using a Plasma color scale to represent population magnitudes. Built with D3 v7 and TopoJSON, it loads countries-110m.json and a CSV population dataset, then renders each country as an SVG path via `d3.geoPath` with a Natural Earth projection. Hover interactions trigger a tooltip displaying country name and population, while a color legend explains the scale. Countries without data appear gray, and the map refreshes with smooth transitions.
