d3-grid-layout

A grid layout for d3.js. The layout gradually expands to fit its nodes/cells within its boundaries.

See the demo for a better explanation.

d3 has a super-intriguing but also perplexing API, so hopefully this lines up with the built-in layouts OK.

Installation

Built for use with browserify - open an issue or pull request if you'd like to use it with something else :)

npm install d3-grid-layout

Usage

gridLayout = require('d3-grid-layout')(d3)

Load up the grid layout by passing it your instance of d3.

grid = gridLayout([nodes])

Create a new grid layout, optionally with an array of data to initiate with.

grid.add(nodes)

Append multiple items to the data array.

grid.push(nodes)

Append a single item to the data array.

grid.sort(comparator)

Sort items in the grid by a comparator function.

grid.width(width)

Set the width of the grid layout.

grid.height(height)

Set the height of the grid layout.

grid.align(dimensions)

Pass a number to change the alignment of the layout, where -1 is top-left, 0 is centered, and 1 is bottom-right.

Alternatively, pass an array for toggling horizontal and vertical alignment (e.g. [-1, 0] is middle-left).

grid.speed(speed)

Change the transition rate when updating the grid layout - defaults to 0.02.

grid.radius(radius)

The maxiumum amount of distance between points in the grid.

grid.nodes(node)

Replace the current set of nodes with a new array.

grid.ease()

Set the easing function. Takes either a custom easing function, or the same arguments as d3.ease.

grid.tick()

Forces an animation tick.

grid.update()

Updates the grid layout - this is done automatically when using grid.add or grid.push, but should be triggered manually otherwise.

grid.cols()

Returns the amount of columns wide the grid is currently.

grid.rows()

Returns the amount of rows high the grid is currently.

grid.size()

Returns an array with the actual width/height of the grid space, e.g. [400, 500].
