Randomly positioned rectangles with "Close" labels demonstrate how D3 v4's drag behavior applies to SVG group elements. Each group contains one rectangle and its text label, which move together during dragging. The example uses `d3.drag()` with `start`, `drag`, and `end` event handlers to update both child elements' `x` and `y` attributes. Data is generated with `d3.range()` and `Math.random()`, while `d3.scaleOrdinal` with `schemeCategory20` assigns colors. The code highlights the challenge of selecting parent `g` elements for unified drag interactions.

AI-generated description

This is an example set up to test the use of the d3.drag component.

The intention is to learn enough about d3.drag to integrate it into a sankey diagram for v4 similar to this example.

The start point was Mikes circle dragging examlpe [here] which I tried to integrate with the object+text drag implimentation here.

Tragically I can't quite work out how to grab the 'g' element and will therefore use this block as an example for a question on Stack Overflow.

EDIT: Spoiler Alert: Solved by Dragon_Slayer. Solution bl.ock here.

d3.drag with grouped elements in v4

This example demonstrates how to use d3.drag in D3 v4 to drag grouped SVG elements together. Ten rectangles with accompanying text labels are generated randomly and placed on a 960×500 SVG canvas. The drag behavior is attached to each `<g>` group, and during the drag event both the rectangle and text are updated simultaneously using `d3.event.x` and `d3.event.y`. The code uses D3 v4’s selection, scaleOrdinal with `schemeCategory20`, and the d3-drag module.

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.

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.

dots

This example displays ten colored rectangles that can be dragged around an SVG canvas. The shapes are randomly positioned and sized using D3’s `d3.range` and `Math.random()`, with each rectangle filled via the `d3.schemePastel1` color scheme. The interactive drag behavior is implemented with `d3.drag()`, which updates the x and y attributes in the `dragged` event and raises the selected element to the front on drag start.

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`.

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.

Click vs. Drag

Twenty colored circles start at random positions. Clicking a circle briefly inflates it to black and back, while dragging moves it to a new location. Using `d3.behavior.drag` with d3.v3, the example distinguishes the two gestures by checking `d3.event.defaultPrevented` in the click handler. The SVG rendering animates transitions for the inflation effect and reorders dragged elements to the front.

Example of zoom and drag in d3 v4.

This example demonstrates how to combine zoom and drag interactions on SVG circles in d3 v4, solving the issue where dragged elements misalign under a zoom transform. It shows 50 randomly positioned circles that remain draggable and correctly track the mouse even when the view is zoomed. The code uses `d3.drag()` and `d3.zoom()` handlers, with a custom drag function that reads the current scale from the circle’s transform attribute to adjust the mouse coordinates. Rendering is done via SVG elements, and the data consists of random x/y positions generated with `d3.range`.
