The example demonstrates zooming and panning over a dense scatterplot of 2,000 points, rendered as red squares that move in response to user interaction. It shows how a standard d3.behavior.zoom can be applied to HTML divs rather than SVG, using CSS transforms for positioning. The code generates random data with d3.random.normal, maps it through linear scales, and updates each square’s transform during the zoom event. The visualization uses d3.v3 with SVG-free HTML elements, highlighting the flexibility of D3’s zoom behavior for non-SVG layouts.

Zoom + Pan

This example demonstrates zooming and panning across a field of 2,000 semi-transparent red squares, whose positions are randomly generated from normal distributions centered in the viewport. The visualization shows how HTML elements can be transformed interactively using D3’s zoom behavior, with the underlying coordinate scales updating in real time. It uses D3 v3’s `d3.behavior.zoom` and linear scales (`d3.scale.linear`) to map data coordinates to screen positions, applying CSS `transform` styles to `<div>` elements. Unlike typical SVG-based examples, this implementation renders the squares as HTML `div` elements, highlighting a lightweight alternative for pan-and-zoom interactions without canvas or SVG overhead.

D3 Zoom

This example demonstrates interactive zooming and panning on a scatterplot of 100 randomly positioned points. Users can scroll to zoom in and out within a scale extent of 0.5x to 4x, or click and drag to pan across the full-window SVG canvas. The visualization uses d3.zoom to attach zoom behavior to the root SVG element and applies the transform directly to that element’s `transform` attribute during the zoom event. Data is generated randomly with the `makeData` utility, and circles are bound and updated using D3’s data join pattern.

Simple Zoom and Pan

This example demonstrates simple zoom and pan interactions on a scatterplot of 100 randomly positioned circles. The visualization uses D3 v4 to render SVG circles with a categorical color scale, while a transparent overlay rectangle captures pointer events and applies a zoom behavior with a scale extent from 0.5× to 4×. The zoomed function updates the transform attribute of a container group, enabling smooth panning and scaling of all circles. The code leverages d3.zoom and d3.event.transform to handle the interaction, with the data generated on the fly using d3.range and Math.random.

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.

Pan & Zoom III + fix

This example shows an interactive scatterplot of 2,000 points arranged in a spiral, which users can pan and zoom by dragging or scrolling over the entire SVG canvas. The visualization relies on the d3-zoom behavior attached to a transparent overlay rectangle, ensuring smooth pointer interaction regardless of the zoomed content. During zooming, the code applies the current transform directly to a group element using the zoom event’s transform property, updating the positions of all circles in real time. The data is generated on the fly with a phyllotaxis function, while the SVG circles are rendered from an array of computed coordinates.

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.

part 2, Zoom and Panning with D3.js and canvas

This example demonstrates zooming and panning across a scatterplot of 10,000 randomly generated points, with axes updating in real time. It uses a Canvas overlay for point rendering and an SVG layer for the axes, both driven by D3 v4’s `d3.zoom` and `d3.zoomIdentity`. A reset button triggers a smooth transition back to the default view. The `rescaleX` and `rescaleY` methods adjust linear scales on each zoom event, while `context.clearRect` and `arc` handle the drawing.

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.
