This example demonstrates improved zoom behavior for a D3.js layout where a background rectangle maintains full coverage of the SVG viewport during pan and zoom operations. It uses the `d3.behavior.zoom` API with a `scaleExtent` of [0.2, 5] to constrain zoom limits. The rescale function applies an inverse transform to the rectangle, using `1 / d3.event.scale` to counteract the group’s scale transformation, ensuring the drag target remains correctly sized and positioned at all zoom levels.

Restricted zoom behavior in d3

This example demonstrates restricted zoom behavior in d3.v5, bounding pan and zoom within a rectangular viewport. A field of 300 randomly positioned and sized circles is rendered in an SVG, and users can scroll to zoom up to 50x and drag to pan; when zooming out to the original scale, the view snaps back to the full extent. The implementation uses `d3.zoom()` with a custom `on("zoom")` handler that clamps translation based on viewport dimensions and scale, then updates the `<g>` element’s `transform` attribute, applying the constrained translation and scale.

Zoom + Pan

This example demonstrates how to pan and zoom a chart using D3.js v3. It renders an SVG with axes and a filled background rectangle, using linear scales for the x- and y- dimensions. The `d3.behavior.zoom` API links the zoom behavior to the scales, allowing mouse wheel and drag interactions to rescale the axes. When zooming occurs, the axes are redrawn to reflect the updated scale ranges. The code sets a zoom scale extent between 1 and 32, and uses `d3.svg.axis` to produce the tick marks and grid lines.

Constrained Zoom

This example demonstrates how to constrain d3-zoom so a rectangular image stays within the viewport during pan and zoom operations, using the `d3.zoom` API and its event handler. The SVG shows a small image element whose bounds are checked against the viewport; the `zoomed` function modifies the transform to prevent the image from moving off-screen. The code calculates the image’s coordinates and uses `scaleExtent` to limit zooming to the viewport size. This implementation relies on the d3.v4 library, rendering via SVG, and handles mouse interactions through the zoom’s event system.

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.

zoom/pan d3v4 - Full

This example demonstrates how to implement zoom and pan interactions on an SVG canvas. The visualization displays a single green circle centered in the viewport, with the zoom behavior applied directly to the SVG group element. The code uses the D3 v4 zoom API via `d3.zoom().on("zoom", zoomfn)` to handle mouse and touch events, and the zoom function applies the event transform to the group. A circle is rendered at the center using `svg.append("circle")`, and the zoom handler updates the group’s `transform` attribute while also calling `svg.scale(4)`, which scales the entire group by a fixed factor. The SVG fills the browser window.

D3 Zoom

A D3 zoom interface demonstrates interactive panning and scaling within an SVG coordinate system. A single green circle, positioned through linear scales, responds to mouse wheel and drag gestures that trigger the `d3.zoom` behavior. The example simultaneously updates axis tick marks via `transform.rescaleX` and `rescaleY`, while displaying the current translation values and zoom multiplier in separate HTML divs. The visualization renders with SVG elements, using `d3.axisBottom`, `d3.axisLeft`, and `d3.scaleLinear` to maintain spatial mapping during the zoom transform.

Zoom + Pan

A zoomable and pannable SVG viewport displays a large grid with axes, controlled by the mouse. The example shows how to programmatically reset the zoom state using a button. It uses d3.behavior.zoom with d3.scale.linear domains, and a transition tween with d3.interpolate to animate the domain reset. The axes and grid are rendered as SVG shapes, and zoomed() rebinds the axes to the updated scales during the transition.

Pan & Zoom Axes

This example demonstrates a zoomable scatterplot where panning and zooming are controlled by the d3-zoom library. The visualization shows a colorful gradient rectangle as the data view, with axes that rescale dynamically through `transform.rescaleX` and `transform.rescaleY`. Users can drag to pan and scroll to zoom, with a button to reset the view via `d3.zoomIdentity`. The SVG rendering uses d3-scaleLinear for axes and a text gradient inspired by Nadieh Bremer.
