A scatterplot of 2,000 normally distributed points demonstrates geometric zooming in SVG. The visualization shows how the entire coordinate system scales uniformly, with all circle radii increasing proportionally as the view magnifies. Built with D3 v4, the example uses `d3.zoom` attached to a background rectangle, applying the current transform directly to a group element containing all points. The code generates random positions via `d3.randomNormal` and renders each point as a circle with a `translate` transform, allowing the zoom handler to scale and pan the whole scene without recalculating individual positions.

SVG Semantic Zooming

SVG semantic zooming applies a zoom transform to the positions of 2,000 circles generated with d3.randomNormal, while keeping their radius constant. The example uses d3.zoom to listen for wheel and drag events, and each circle’s transform attribute is updated via a custom function that applies d3.event.transform to its datum coordinates. A transparent overlay rectangle captures pointer events, and the circles are rendered as SVG elements with a fixed radius of 2.5 pixels, demonstrating how semantic zoom scales positions without altering symbol size.

Canvas Geometric Zooming

This example demonstrates geometric zooming on a canvas, where a scatterplot of 2,000 normally distributed points scales and translates as a unified image. The code uses d3.zoom with scaleExtent to handle user interaction, applying the transform directly to the canvas context via translate and scale methods. Points are drawn using the Canvas 2D API’s arc and fill operations, while the underlying data is generated with d3.randomNormal. Unlike semantic zooming, this approach redraws the entire visualization at the new scale, preserving the spatial relationships between all marks.

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.

Canvas Geometric Zooming

This example demonstrates geometric zooming on a canvas, where a scatterplot of 2,000 normally distributed points scales and translates as a single unit. The code uses D3 v4’s `d3.zoom` to handle user input, applying the transform directly to the canvas context via `translate` and `scale`. Points are drawn with the Canvas 2D API’s `arc` method, and the zoom behavior redraws all points on each event. No semantic distortion occurs—the entire visualization scales uniformly.

Pan & Zoom IV

Two thousand circles laid out in a phyllotaxis spiral show the d3.zoom behavior applied by directly manipulating each circle’s SVG transform attribute. On every zoom event, the code calls *transform*.applyX and *transform*.applyY to remap the original data coordinates, keeping all circle radii constant at 2.5 pixels while allowing pan and zoom between half and four times the initial scale. This approach, written in d3.v4 with SVG, demonstrates an alternative to scaling a single parent group, trading performance for customization.

Pan & Zoom III

A sparse scatter plot of 2,000 points arranged in a phyllotaxis spiral demonstrates interactive pan and zoom via the `d3.zoom` module, which applies an SVG transform to a group element upon zoom events. The behavior is attached to an invisible overlay rectangle, and the visible circles remain static while the group’s transform updates. The code uses `d3.select`, `d3.range`, and the `phyllotaxis` function to generate the spiral 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.

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.
