Forked from Map

This choropleth map visualizes global GDP per capita using a logarithmic color scale, with countries colored from dark to light based on economic output. Hovering over any country reveals a tooltip showing its name and exact GDP value. The visualization uses D3 v7 with `d3.geoNaturalEarth1` projection and `d3.geoPath` to render world geography from TopoJSON data, while `d3.scaleSequentialLog` with the Plasma interpolator handles color encoding. A graticule layer and interactive legend complete the SVG-based rendering.

This visualization presents global GDP data for 2022 on an interactive world map. Countries are colored using a sequential logarithmic scale with the RdYlGn interpolator, where hovering reveals tooltips with country names and values. A second map displays countries with rainbow-hued fills using d3.scaleSequential with interpolateRainbow, also featuring interactive tooltips. Both maps use d3.geoPath with different projections (geoEqualEarth and geoNaturalEarth1), loading geographic data from world-atlas TopoJSON and economic data from a CSV file.

d3 choropleth (world) map

This choropleth map visualizes average GDP per capita by country from 1970 to 2017, with each nation shaded on a logarithmic green color scale based on its value. Hovering over a country dims all others, highlights the selected region, and reveals a tooltip with the country’s name and GDP. Built with D3 v6, it uses `d3.geoMercator` and `d3.geoPath` to project and draw the map from a simplified GeoJSON, while the data from a CSV is joined to the topology for coloring. Animated transitions control opacity and tooltip visibility.

Choropleth Map

This choropleth map visualizes GDP per capita (PPP, current international $) for 2020 across countries, using a sequential YlGnBu color scale to encode economic output. The map renders with d3.geoNaturalEarth1 and d3.geoPath, while d3.scaleQuantile assigns colors from d3-scale-chromatic’s schemeYlGnBu. Data comes from a World Bank CSV parsed with d3.csvParse, and country boundaries use topojson-client on a world atlas. Gray fills indicate missing GDP values for a given country.

GDP Choropleth Viz

A world map colored by GDP per capita displays each country’s economic standing for a selected year, controlled by a slider. Hovering over a country updates a line plot showing that nation’s GDP trend over time, with red and green reference lines marking the current year’s value. The visualization combines a `d3.geoEqualEarth` projection rendered as SVG with `d3.scaleLinear` color encoding, alongside a linked line chart built using `d3.line` and axis components. GDP data originates from a CSV file, while country boundaries use a GeoJSON source.

ICE-8 1A kumar danam

This choropleth map visualizes a small dataset of numeric values for selected countries using a dark-to-light blue-green color scale. It displays world country boundaries from the `world-atlas` TopoJSON source, rendered as SVG paths via `d3.geoPath` with a Natural Earth projection. The map uses `topojson.feature` to process countries, `d3.scaleSequential` with an `interpolateYlGnBu` scheme for coloring, and a legend built with `d3.axisBottom`. Hovering over a country reveals its ISO numeric ID and value via a tooltip, with missing data shown in gray.

ICE-8

ICE-8 presents a pair of interactive SVG choropleth maps showing world GDP and US state values. The world map projects Natural Earth TopoJSON countries with a Natural Earth projection and uses a green sequential color scale, while the US map uses an Albers USA projection. Both maps use `d3.geoPath`, TopoJSON features, and tooltip interactions. Data is joined from remote CSV sources, with JavaScript fetch and D3’s data loaders handling URL fallbacks.

ICE-8

A world choropleth maps country-level numeric values from a CSV file onto a natural Earth projection, using a plasma color scale and gradient legend to encode magnitude. The visualization links ISO numeric country codes to TopoJSON geometry from the world-atlas dataset, rendering with D3 v7’s `d3.geoPath`, `d3.geoNaturalEarth1`, and `d3.scaleSequential`. Hovering over a country reveals a tooltip with its name and value, while countries without data appear in a muted blue.

ICE 8 (1)

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.
