grid-graph

Built from component template at https://github.com/gojutin/svelte-custom-element.

Usage

grid-graph is a custom element that should be possible to use in any web framework and also in plain html.

Example

<grid-graph nodes="..." connectors='...'/>

nodes should be a json-encoded string containing a two-dimensional array of nodes. Each node is an object with the following properties:

• id - an identifier for the node. Used as the label of the node and when defining connectors.
• color - optional text-color for the node. Default #383d41
• background - optional background for the node. Default #e2e3e5.
• border - optional border for the node. Default none.

;[[{ id: 'A' }, { id: 'B' }], [undefined, { id: 'C' }]]

connectors shall be an array of connector objects. Each connector object has the following properties:

• from - the id of a node
• to - the id of a node
• color - the color of the connector. Default: #444.

;[{ from: 'A', to: 'B' }, { from: 'A', to: 'C' }]

The grid-graph element emits a nodeclick whenever the user clicks a node, with the id of the node in event.detail.nodeId.

See public/index.html for a complete example.

See @mattiash/grid-graph-placement for a module that automatically places out your nodes on a grid.

Styling

The grid-graph can be styled with css variables.

<grid-graph style="--node-margin: 5px 30px; --node-padding: 2px 10px">
</grid-graph>
