This interactive world map displays country boundaries and allows users to hover over each country to see its ISO numeric ID in a tooltip and click to zoom in on it. The visualization uses D3.js v7 with the `d3.geoNaturalEarth1` projection and `d3.geoPath` to render the map, loading TopoJSON data from the world-atlas CDN and converting it to GeoJSON features with the `topojson-client` library. A graticule grid is overlaid, and animated zoom transitions are handled with the `transition` method. The map supports a reset button to restore the initial zoom level.

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.

Activity 8 Map

This interactive world map displays country boundaries using a light green fill on a sky-blue sphere, with indigo strokes and a maroon hover effect. The visualization loads GeoJSON data from the world-atlas TopoJSON file via `d3.json`, converts it with `topojson.feature`, and renders paths using `d3.geoPath` with a `geoEquirectangular` projection. Users can pan and zoom through `d3.zoom`, which applies transforms to the SVG. The map is built with D3 v5 and styled through a linked CSS file.

World map

This interactive world map displays country boundaries using a natural Earth projection, with hover tooltips showing country names and zoom/pan controls for exploration. It loads geographic data from the world-atlas TopoJSON and TSV files, then renders countries with D3’s `geoPath` and `geoNaturalEarth1`. The visualization uses `d3.zoom` for interaction and `topojson.feature` to convert TopoJSON geometry, with hover effects styled via CSS.

Map Interaction Assignment

This example shows an interactive world map where each country is rendered as a filled path, and hovering over a country turns it red. The map uses a natural Earth projection via `d3.geoNaturalEarth1` and `d3.geoPath`, with country boundaries loaded from TopoJSON data in the world-atlas package. Zoom and pan interactions are implemented using `d3.zoom`, which applies a transform to the map group. Country names are matched from ISO codes in a TSV file and displayed as tooltips using SVG `<title>` elements.

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.

Let's make an interactive map with D3.js!

This interactive map visualizes world countries with hover highlighting, displaying country names as tooltips. It uses the D3.js v5 library with the `geoNaturalEarth1` projection and `geoPath` for rendering map features. The visualization loads geographic data from the world-atlas package, combining TSV metadata and TopoJSON geometry, while `topojson.feature` processes the country boundaries. The map supports zooming through D3’s `zoom` event, and renders as an SVG with styling for the ocean sphere and landmasses.

Activity 8 Map

This example displays an interactive world map using D3 v5 and TopoJSON. It renders country boundaries from the world-atlas dataset (countries-110m.json) as SVG paths via d3.geoPath and d3.geoEquirectangular projection. Zoom and pan interactions are enabled through d3.zoom, which applies SVG transforms. The map colors landmasses light green with indigo strokes and turns them maroon on hover, demonstrating local ES6 module imports and D3’s data join pattern.

Activity 8 Map

This interactive world map uses D3.js to render country boundaries from the world-atlas TopoJSON data. The visualization displays continents in light green with indigo borders against a skyblue ocean sphere using an equirectangular projection. The map supports pan and zoom interactions through D3's zoom and event APIs, while hover states are implemented via CSS to change country colors to maroon. The code demonstrates importing D3 modules and a local ES6 module, and uses the topojson library's feature method to convert the data into GeoJSON.
