Clicking a US state zooms the map to that state with a smooth transform transition, dims all other states, and applies a drop-shadow filter to highlight the selected state. Clicking the background resets the view and restores full opacity. The example renders SVG paths from TopoJSON state boundaries using `d3.geo.path` and an Albers USA projection, animating the zoom with `transition.attr`. A custom `moveToFront` selection method brings the active state to the top of the SVG stack.

click-to-zoom via transform

Clicking a US state zooms to that state via a SVG transform transition, while clicking the background resets the view. The map renders TopoJSON data through `d3.geo.albersUsa` projection and `d3.geo.path`, with state borders drawn from a topology mesh. An orange highlight marks the active state, and stroke width inversely scales with zoom. The interaction uses a `g.transition()` to animate `translate` and `scale` attributes over 750 milliseconds.

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 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

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 in Map Demo

Clicking a US state zooms to that state at 4× magnification, while clicking again resets the view. Clicking an individual county zooms in much deeper, to 23×, centering on that county. Built with D3 v3 and TopoJSON, the map renders US states and counties as SVG paths using an Albers USA projection, with smooth 750-millisecond transitions handled by D3's `transition` and `attr` methods. The data comes from a raw GitHub gist containing US TopoJSON topology.

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.
