TEST

An interactive orthographic globe displays graticule lines, a red rectangular arc region, and a sphere outline, with a hidden world map loaded for future rendering. Users drag to rotate the projection via `d3.drag`, adjusting the rotation with `projection.rotate`, and zoom using `d3.zoom` to transform the SVG group. The visualization uses `d3.geoOrthographic`, `d3.geoPath`, and `d3.geoGraticule`, fetching TopoJSON from the world-atlas package, while styling SVG paths with CSS classes for the sphere, graticule, and rectangle.

Global zoom pan

This example shows an orthographic globe that responds to both dragging and zooming. Drag gestures rotate the projection, while zooming scales the globe’s size. The visualization uses a d3.geoOrthographic projection with a d3.geoPath renderer to draw world country boundaries from a GeoJSON file hosted by visionscarto.net. Interaction is handled via d3.zoom for scaling and d3.drag for rotation, with linear scales mapping screen coordinates to latitude and longitude offsets. The globe’s sphere is rendered as a light blue background, and a single orange point marks a specific coordinate.

Orthographic Zoom II

This example demonstrates panning and zooming on an orthographic globe projection, allowing users to rotate the Earth by dragging and scale it with a zoom gesture. Building on a prior version, it improves panning accuracy by accounting for latitude during the rotation adjustment. The implementation uses D3 v4 with `d3.geoOrthographic` and `d3.geoPath` for rendering, alongside `d3.drag` and `d3.zoom` for interaction. Landmasses come from the `world-110m` dataset in TopoJSON format, and the globe is drawn as SVG paths.

Orthographic Zoom I

This example presents an interactive orthographic projection of the world, allowing users to rotate the globe by dragging and zoom in and out with the mouse wheel. It visualizes land polygons from the `world-110m` TopoJSON dataset. The code uses `d3.geoOrthographic` and `d3.geoPath` to render shapes, with `d3.drag` handling rotation and `d3.zoom` adjusting the projection scale.

Orthographic Zoom III

This interactive globe displays country boundaries using an orthographic projection, panning and zooming smoothly with the mouse. During interaction, it renders the lower-resolution 110m world-atlas dataset, then switches to the higher-resolution 50m dataset once the motion stops for crisp detail. Built with D3 v4, it uses `d3.geoPath` and TopoJSON to project geographic features, with drag and zoom behaviors from `d3.drag` and `d3.zoom` controlling the globe's rotation and scale.

Orthographic Grid

An orthographic grid of graticule lines at 10-degree intervals rotates slowly over time, demonstrating an azimuthal projection that resembles a globe viewed from space. The visualization uses D3 v3’s `d3.geo.orthographic`, `d3.geo.path`, and `d3.geo.graticule` to render SVG paths, while a `d3.timer` continuously updates the projection’s rotation based on a fixed velocity vector. A static circle outlines the globe’s edge, and the animation shows how latitude and longitude lines curve as the view shifts.

Fork of Panning & Zooming on a Globe

This example shows an interactive orthographic globe that can be panned by dragging and zoomed with the mouse wheel. Dragging rotates the projection based on drag distance and scale, while zooming adjusts the projection’s scale factor. The globe renders country boundaries from the `world-atlas` TopoJSON dataset using `d3.geoOrthographic` and `d3.geoPath`. User interaction is handled through `d3.drag` and `d3.zoom`, with rendering updating dynamically on each event.

Panning & Zooming on a Globe - old

This example shows an interactive orthographic globe that supports panning and zooming. Users drag to rotate the Earth and use the mouse wheel to scale the projection. The visualization renders world landmasses from TopoJSON data using `d3.geoOrthographic` and `d3.geoPath`. Panning is implemented with `d3.drag` to adjust the projection’s rotation, while zooming uses `d3.zoom` to modify its scale. The code also uses `d3.select` and `d3.json` to load and render the geographic features.
