Choropleth map

Choropleth Map

A choropleth map colors countries by their economic classification using an ordinal color scale with a spectral scheme. The visualization loads world geometry from TopoJSON and country metadata from TSV, joining them by ISO numeric codes, and renders with D3’s `geoNaturalEarth1` projection and `geoPath`. A custom `colorLegend` displays the scale, while zooming and panning are enabled via `d3.zoom`. Hovering highlights countries, and tooltips reveal name and economy class.

Choropleth Map

A choropleth map colors countries by economic category using an ordinal color scale with a spectral palette. The visualization loads world geometry and country metadata from the world-atlas TopoJSON and TSV files, rendering paths with `d3.geoPath` and a Natural Earth projection. Users can pan and zoom via `d3.zoom`, while a custom legend built with D3 selections displays color categories as circles and text. Hovering highlights a country in red, and tooltips show each nation's name and economy type.

Choropleth Map

A choropleth map colors countries by economic classification using an ordinal color scale derived from world-atlas data. The visualization renders geographic boundaries with `d3.geoPath` and a natural Earth projection, while a custom color legend explains the categorical mapping. Pan and zoom interactions are enabled via `d3.zoom`, and hover effects highlight individual countries. The map uses TopoJSON for country outlines and TSV metadata for economy labels.

YYF

Choropleth Map

A choropleth map colors countries by their economic classification, with a color legend showing ordinal categories from the Spectral scheme. The visualization loads world geometry from TopoJSON and joins it with tabular data from a TSV file. Using d3.geoPath with a geoNaturalEarth1 projection, it renders SVG paths that support zooming via d3.zoom. Hovering highlights individual countries, while a custom colorLegend component displays the color scale with circles and text labels.

Ccaydener

Choropleth Map

This choropleth map colors countries by economic classification using a categorical ordinal scale with the Spectral scheme. It loads world geometry from TopoJSON and joins it with TSV metadata, then renders the map with d3.geoPath and a Natural Earth projection. The visualization includes an interactive color legend built with custom SVG components, and supports zooming and panning through d3.zoom. Hovering highlights individual countries in red, and tooltips display each country’s name and economic group.

Ddata-inside

Choropleth Map

A choropleth map colors world countries by economic classification using a sequential ordinal scale and the Spectral color scheme. The visualization, built with D3 v5 and TopoJSON, renders countries as SVG paths via d3.geoPath with a Natural Earth projection, supporting zoom and pan. A custom color legend displays the categorical color scale, while country data is joined from the World Atlas TopoJSON and TSV datasets using Promises.

Xxhoumba

Choropleth Map

This choropleth map colors countries by their economic classification using a spectral color scale, with hover highlighting and zoom/pan enabled via d3.zoom. The visualization loads world geometry from TopoJSON and joins it with tab-separated country metadata from the world-atlas dataset. It renders geographic paths with d3.geoPath and a Natural Earth projection, while a custom color legend displays ordinal color domains using SVG circles and text.

NNilla

Choropleth Map

This choropleth map visualizes countries colored by their economic classification, using a spectral color scale to distinguish categories. The map renders geographic boundaries as SVG paths via `d3.geoPath` and a Natural Earth projection. Data is loaded from the World Atlas TopoJSON and TSV files, merged by country ID, then assigned to the `d3.scaleOrdinal` color scale. A custom legend shows color swatches with labels, and hovering highlights individual countries in red. Interaction includes zoom and pan through the `d3.zoom` event, which applies an SVG transform.
