Pan

World Map: Hover and Zoom/Pan

This example presents an interactive world map rendered in SVG using D3 v5, supporting hover effects and zoom/pan navigation. Users can explore geographic regions by moving the cursor or dragging to reposition the view, with zoom controls enabling closer inspection of specific areas. The visualization employs a projection-based mapping approach, where the map is drawn using `d3.geoPath` and geographic data is transformed into screen coordinates. Interaction is handled through D3's event system and zoom behavior, while the page layout uses fixed positioning CSS to maintain full viewport coverage for the interactive canvas.

Map Pan & Zoom II

This example demonstrates interactive pan and zoom on a world map using a dynamic Mercator projection. The map renders country landmasses as black paths, with white boundaries and a light gray sphere background, all within an SVG element. Using the `d3.behavior.zoom` API, user drag or scroll actions trigger reprojection and redraw the geospatial data via `d3.geo.path`. The underlying geographic data is loaded as JSON from a gist, and the projection translates and scales dynamically with each zoom event.

Zooming and Panning

Four multicolored circles arranged in a square pattern sit at the center of an SVG canvas. The visualization demonstrates zooming and panning through d3.behavior.zoom, which captures mouse wheel drags and touch gestures. Users can scale the view between 1× and 10× magnification and pan freely by dragging. The circles’ positions are defined in data arrays and rendered as SVG circle elements with a translate transform applied to the parent group during zoom events.

Zoom + Pan

This example demonstrates zooming and panning across a 2D Cartesian coordinate system with visible axes. The view initially centers on the origin, and the user can pan by dragging and zoom by scrolling, with the axis tick marks and grid lines updating accordingly. A "Reset" button restores the original scale and translation. The implementation uses d3.behavior.zoom with linear scales for the x and y axes, and calls the axis render functions within the zoom event handler. The SVG rendering includes a light gray background rectangle and white axis strokes.

Map Pan & Zoom IV

This example demonstrates fast map panning and zooming on a Canvas. It uses pre-projected geometry from a `world.json` file, rendered via d3.geo.path. Pan and zoom use `d3.behavior.zoom`, with dynamic simplification via a custom `d3.geo.transform` and viewport clipping via `d3.geo.clipExtent`. The map shows country boundaries and a sphere outline.

DOM panzoom demo

This example demonstrates pan-and-zoom interaction on DOM elements. A page of placeholder Latin text can be dragged and scaled using the `panzoom` library, which manipulates CSS transforms. The rendering uses plain HTML and D3 v5 for setup, while the interaction logic relies on the external `panzoom` API. The visualization is purely a DOM manipulation demo, with no data binding or charting involved.

Map Pan & Zoom III

A world map rendered on a Canvas element supports pan and zoom interactions via the d3.behavior.zoom API. The map uses pre-projected geographic geometry from a TopoJSON file, with d3.geo.path using a null projection so that only the canvas transform changes during zoom, avoiding re-projection. Country boundaries and land masses are drawn as filled and stroked paths, with strokes scaled inversely to maintain constant width.

Zoom + Pan

This example demonstrates interactive zooming and panning on a simple coordinate grid with axes, controlled both by mouse gestures and on-screen buttons. The visualization uses d3.behavior.zoom to link the scale domains to user input, with the axes redrawn on each zoom event. Button clicks trigger animated transitions that adjust the zoom scale or translate the view, recalculating the center point in data space to maintain focus. The rendering uses SVG with d3.v3, and the code explicitly handles coordinate conversion between screen and data space via the zoom object's scale and translate properties.
