Clicking a US state zooms the map to that state’s bounding box, with a smooth 750-millisecond transition, while the user can also freely pan and zoom. The example uses d3.v4’s `d3.zoom` and `d3.geoPath` with an Albers USA projection, rendering state features as SVG paths from TopoJSON. Zooming is triggered by computing the path bounds and applying `d3.zoomIdentity.translate().scale()` via `transition.call(zoom.transform)`. Clicking the background resets the view, and active states highlight in orange, with the mesh and stroke width updating on zoom.

AI-generated description

Updated variant of Zoom to Bounding Box II for d3 v4 which is also a variant of the Zoom to Bounding Box example that uses zoom transitions to smoothly interpolate between different views. This example also allows you to freely pan and zoom with the mouse (or touch).

Zoom to Bounding Box

Clicking any U.S. state zooms the Albers USA projection to that state’s bounding box, while clicking the background or the active state resets the view. The code computes the path bounds via `d3.geo.path` and uses a `g.transition()` with a computed translate and scale to animate the viewport, adjusting stroke widths inversely to the zoom. It loads TopoJSON state boundaries and uses D3 v3’s `d3.geo.albersUsa` projection, rendering SVG paths with click handlers for interactivity.

Zoom to Bounding Box II d3v4

This example demonstrates zooming and panning across a map of the United States, with clickable states that smoothly transition to fill the viewport. It shows how to combine geographic projections with D3’s zoom behavior for interactive exploration. The visualization uses `d3.geoAlbersUsa` for the projection, `d3.geoPath` to render TopoJSON state boundaries, and `d3.zoom` to handle free pan and zoom. Clicking a state triggers a 750ms transition via `zoom.transform`, calculating a bounding-box scale and translate to frame the feature. The active state is highlighted in red, while stroke widths adjust inversely to the zoom level for crisp rendering.

Zoom to Bounding Box II - test

This example demonstrates a zoomable and pannable map of U.S. states, where clicking a state smoothly transitions the view to center and scale that state’s bounding box. It shows how to combine free-form zooming and panning with programmatic animated transitions. The visualization uses D3 v3 with the `d3.geo.albersUsa` projection, `d3.geo.path` for rendering GeoJSON features, and `d3.behavior.zoom` for user interaction. Clicking a state triggers a 750-millisecond zoom transition, while a background click resets the view. State boundaries are drawn as a TopoJSON mesh, and the map data comes from a TopoJSON file of U.S. states.

Zoom to Bounding Box II

This example demonstrates smooth zooming and panning over a map of the United States using Albers equal-area projection. Users click individual states, triggering a 750-millisecond animated transition to a bounding box around that state, while the map remains freely navigable via mouse drag and wheel zoom. The visualization uses `d3.geo.albersUsa` for projection, `d3.behavior.zoom` for interactive and animated transformations, and `d3.geo.path` to render state boundaries and a mesh overlay from the US TopoJSON data file. Active states highlight in orange, and stroke widths adjust dynamically during zoom.

click-to-zoom via transform

Clicking a US state smoothly zooms the map to that state, centering it and enlarging it fourfold; clicking again restores the full national view. The example builds an interactive state map with D3, using `d3.geo.albersUsa` for the projection and `topojson` to process geographic data. Zoom animation is driven by D3 transitions, which update an SVG `g` element’s `transform` attribute and adjust the stroke width to maintain visual consistency. State borders and a clickable background rect facilitate the interaction, with active states highlighted in orange.

Zoom to Bounding Box II d3v4

This interactive map of the United States supports both click-to-zoom and free pan/zoom via mouse or touch. Clicking a state smoothly zooms to its bounding box, while a mesh overlay shows state borders. It uses `d3.geoAlbersUsa` for the projection, `d3.geoPath` for rendering, and the `d3.zoom` transition to interpolate between views. The map data comes from a remote TopoJSON file, and the SVG rendering animates transformations and stroke widths.

Zoom to Bounding Box II

This interactive map of the United States lets users click any state to zoom smoothly to its bounding box, while also supporting free pan and zoom via mouse or touch. The visualization uses D3.js v3 with an AlbersUSA projection and TopoJSON state boundaries, rendered as SVG paths. Clicking a state triggers a 750-millisecond zoom transition, adjusting the zoom behavior’s scale and translate to fit the selected feature, while the active state highlights in orange. The zoomed function updates the group’s transform and stroke width inversely with scale, and the background rectangle resets the view when clicked.
