Map Interaction Assignment

Map Interaction Assignment

This interactive map visualizes global country boundaries using a natural Earth projection, rendered as SVG paths within a zoomable viewport. The map shows the sphere as a blue background and individual countries in green, which turn red on hover, with country names displayed as tooltips. Built with D3 v5, the example uses `d3.geoNaturalEarth1`, `d3.geoPath`, and the `topojson` library’s `feature` function to process world atlas data loaded from TSV and JSON files. A zoom interaction, implemented via D3’s `zoom` event, transforms the map group, allowing users to explore the geographic data.

Map Interaction

This example displays an interactive world map rendered with SVG using the d3-geo-projection library, specifically the geoNaturalEarth1 projection. Countries from the world-atlas TopoJSON dataset are drawn as paths with d3.geoPath, each featuring a tooltip showing the country name. The map supports pan and zoom through d3.zoom, which applies a transform to the map group on events. Hovering over a country changes its fill color to red via CSS, while the sphere background uses a distinct blue fill.

Map Interaction

This example displays an interactive world map, rendering country boundaries as SVG paths using d3.geoPath and a d3.geoNaturalEarth1 projection. The map is built from TopoJSON data loaded via d3.json and the topojson.feature API, with country names attached as SVG title elements. The visualization supports panning and zooming through d3.zoom, which applies a transform to the map group, and highlights individual countries by changing their fill color on hover using CSS.

Map Interaction Assignment

This map displays global country boundaries over a blue sphere, with hover interactions highlighting each nation in red. Panning and zooming are enabled via d3.zoom, which applies transforms to the geographic group. The visualization loads TopoJSON world data from the world-atlas package, converts it to GeoJSON with topojson.feature, and renders paths using d3.geoPath with a d3.geoNaturalEarth1 projection. Hover tooltips appear through appended SVG title elements, which draw country names from the accompanying TSV data file.

Map Interaction Assignment

This visualization displays a world map using a natural Earth projection, with countries shaded in light green and oceans in blue. Clicking a country triggers an interaction where the selected country turns red, highlighting the user’s choice. The map is rendered as SVG, with geographic data from the world-atlas TopoJSON dataset and country names loaded from a TSV file. The code utilizes d3.geoPath, d3.geoNaturalEarth1, and d3.zoom, along with topojson.feature to process the data.

Map Interactions

This example displays an interactive world map using a natural Earth projection, with countries rendered as light green SVG paths that turn teal on hover. The visualization combines world-atlas TopoJSON data with a TSV file containing country names, which are added as native SVG `<title>` tooltips. The map supports pan and zoom through d3.zoom, while d3.geoPath and d3.geoNaturalEarth1 handle geographic projections. Hover effects use CSS pseudo-classes, and the map includes a blue sphere background for context.

Map with interaction

This example shows an interactive map of world countries rendered as SVG paths using the Natural Earth projection. Users can pan and zoom the map via d3.zoom, which applies a transform to the grouped map elements. The map loads GeoJSON data from the world-atlas TopoJSON file, converts it with topojson.feature, and draws each country using d3.geoPath. Countries fill light green and turn red on hover, with the surrounding sphere rendered in blue. The visualization demonstrates basic geographic mapping with interactive zooming and hover feedback.

Map Interaction Assignment

This map displays the countries of the world, color-coded by continent, and shows each country's name, continent, and broader economic position in a tooltip on hover. It uses a natural Earth projection via `geoNaturalEarth1` and renders geographic paths with `geoPath`, while `topojson.feature` converts the TopoJSON source into renderable features. Users can pan and zoom the map, with the interaction handled by the `zoom` API, which applies a transform to the entire group of country paths. Hovering highlights a country by filling it yellow.
