Twenty colored circles move freely over a full-window SVG canvas. Each circle is draggable with a multitouch pointer, and its position updates live to follow the finger. The code uses `d3.behavior.drag` with `dragstart`, `drag`, and `dragend` handlers to manage interaction, while `d3.select` and `.transition().ease("elastic")` animate the radius from 32 to 48 pixels on grab and back on release. Random starting coordinates come from `d3.range(20).map()`.

Multitouch Drag II

Twenty colored divs drift across the browser window, each rendered as a circle via CSS border-radius and positioned using a CSS transform translate. Dragging a circle with a mouse or touch lifts it visually: it expands, gains a soft box-shadow, and uses an elastic ease during the size transition. The implementation uses D3 v3’s `d3.behavior.drag` for pointer handling, `d3.scale.category10` for colors, and `d3.interpolate` to animate box-shadow between drag states. Data is randomly generated from 20 coordinate pairs.

Drag circles

Five colored circles are positioned in a row on an 800×480 SVG canvas, each with a radius of 60 pixels. The example demonstrates a basic drag-and-drop interaction using D3.js v4, where users can move any circle freely by clicking and dragging it. The circles change cursor to a move icon on hover and gain a black outline while being dragged. The code uses `d3.drag()` with `dragstarted`, `dragged`, and `dragended` handlers, along with `d3.scaleOrdinal` and `d3.schemeCategory20` for coloring, and `d3.select(this).raise()` to bring the active circle to the front.

Multitouch

This multitouch visualization maps each finger contact to a colored circle on an SVG canvas, with touches tracked by identifier. The example uses D3’s `d3.touches` API to capture touch events and `d3.event` to prevent default scrolling. Newly detected touches enter with an elastic scaling animation via `transition.attr("r", …)`, while removed touches shrink and exit. Circle positions update directly from touch coordinates, and color assignment uses `d3.scale.category10`. The code relies on touch-supporting browsers, such as iOS Safari, to dispatch the appropriate events.

Circle Dragging I

This example shows a set of colored circles scattered across an SVG canvas, which users can drag with the mouse. Each circle’s position is stored as x and y properties in its data object, and those values update live during the drag. The code uses d3.select and d3.drag from the d3-drag module to handle the interaction, attaching event handlers for start, drag, and end. At drag start, the circle is raised to the foreground with `.raise()` and gets a black stroke via the `.active` class; the stroke is removed on release. The circles are rendered as SVG `<circle>` elements, colored with a categorical scheme from `d3.scaleOrdinal` and `d3.schemeCategory20`, with random initial positions computed from the SVG’s dimensions.

Circle Dragging II

This example shows a canvas-based visualization where users can drag any of twenty randomly positioned circles. It uses the d3.drag module with a custom subject function for hit-testing, checking if the pointer falls within a circle’s radius. During a drag, the circle is reordered to the foreground, marked with a temporary stroke, and its position updates, triggering a redraw via render listeners. The implementation relies on D3 v4’s event handling, Canvas’s 2D context, and d3.scaleOrdinal with the schemeCategory20 palette for circle fill colors, producing smooth, interactive feedback.

Drag Multiples

A grid of sixteen small SVG circles, each in its own separate SVG element, can be dragged independently within the bounds of its cell. The example demonstrates the `d3.behavior.drag` API, using its `origin` accessor and `drag` event to update circle positions. Each circle is constrained to its local coordinate space, with position clamped between the radius and the SVG width or height. The code uses d3.v3 and renders the visuals as SVG, with the data derived from a static array of sixteen identical starting points.

Drag Multiples

Sixteen identical SVG panels each display a gray circle that a viewer can drag within the panel’s boundaries. The circles are initially centered and constrained by the panel’s dimensions and the circle’s radius. The d3.behavior.drag() API handles the drag interaction, updating each circle’s cx and cy attributes based on the mouse event’s x and y positions. The code uses d3.select and d3.range to create the panels and data objects, with d3.event providing the current pointer coordinates.

Click vs. (a great deal of) Drag(ging)

Twenty colored circles are rendered in an SVG, where each circle can be either clicked or dragged. A click triggers a two-step radius animation (expanding to 64, then shrinking back to 32), while dragging moves the circle and, once the drag exceeds a small threshold, brings the circle to the front using `raise()` and adds an active class. The example uses D3 v4’s `d3.drag()` with `.clickDistance(4)` to distinguish clicks from drags, alongside manual checks on `sourceEvent` coordinates to handle edge cases where the drag ends near the start point. Data is generated randomly as an array of 20 `{x, y}` objects, with colors assigned via `d3.scaleOrdinal` and `d3.schemeCategory20`.
