Clicking a U.S. state zooms the map to that state’s bounding box, with a smooth 750-millisecond transition, while a gray mesh outlines all state boundaries. The view also resets to the full country when clicking the background. Built with D3 v4, the example uses `d3.zoom` with a `translateExtent` that constrains panning, `d3.geoPath` and `d3.geoAlbersUsa` for rendering TopoJSON state features as SVG paths, and `zoom.transform` to animate the zoom. The active state highlights in orange, and stroke widths scale inversely with the zoom level.

Zoom to bounding box d3.v4

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.

Zoom to Bounding Box

This interactive map of the United States uses D3.js (v3) with the Albers USA projection to render state boundaries as SVG paths. Clicking a state triggers a smooth 750-millisecond transition that computes the clicked feature's bounding box and applies a translate and scale transform to zoom into it. The zoom level and translation are calculated using the `d3.geo.path` bounds method, with stroke widths adjusted inversely to the scale. Clicking the active state or the background resets the viewport to its original full-country extent.

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 d3v4

A choropleth-style map of U.S. states loads with a free pan-and-zoom interface. Clicking a state smoothly zooms to fit that state’s bounding box using a 750-millisecond transition, while a red highlight marks the active state; clicking the background resets the view. The visualization uses D3 v4’s `d3.zoom`, `d3.geoPath` with an Albers USA projection, and TopoJSON state boundaries. Zoom transitions interpolate between `d3.zoomIdentity` transforms, and stroke widths scale inversely with the zoom level for crisp rendering.

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 - 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.
