|
### JavaScript
|
||||||
|
```js

import("/js/modules/graph.mjs").then((graph) => {
|
||||||
|
// Imported the graph.mjs module
|
||||||
|
|
||||||
|
// Initializing the graph instance
|
||||||
|
const instance = new graph.core(document.getElementById('graph'));
|
||||||
|
|
||||||
|
// Writing settings of the graph instance
|
||||||
|
instance.living = 3000;
|
||||||
|
instance.camera = true;
|
||||||
|
instance.operate = true;
|
||||||
|
|
||||||
|
// Initializing and registering nodes
|
||||||
|
const genesis = instance.node(new graph.node(document.getElementById('genesis')));
|
||||||
|
const food = instance.node(new graph.node(document.getElementById('food')));
|
||||||
|
const tofu = instance.node(new graph.node(document.getElementById('tofu')));
|
||||||
|
const broccoli = instance.node(new graph.node(document.getElementById('broccoli')));
|
||||||
|
const wtf = instance.node(new graph.node(document.getElementById('wtf')));
|
||||||
|
const bebra = instance.node(new graph.node(document.getElementById('bebra')));
|
||||||
|
const feet = instance.node(new graph.node(document.getElementById('feet')));
|
||||||
|
const anarchy = instance.node(new graph.node(document.getElementById('anarchy')));
|
||||||
|
|
||||||
|
// Writing settings for every node
|
||||||
|
instance.nodes.forEach((node) => { node.variables.get("inputs").type = "deg" });
|
||||||
|
|
||||||
|
// Initializing and registering edges
|
||||||
|
instance.edge(new graph.edge(feet, bebra));
|
||||||
|
instance.edge(new graph.edge(bebra, genesis));
|
||||||
|
instance.edge(new graph.edge(anarchy, genesis));
|
||||||
|
instance.edge(new graph.edge(food, genesis));
|
||||||
|
instance.edge(new graph.edge(tofu, food));
|
||||||
|
instance.edge(new graph.edge(broccoli, food));
|
||||||
|
