createGraph doesn't exist

[otse]

There's no createGraph function to be found anywhere!

The module's ambient file only exposes three functions

export function aStar, aGreedy and nba.

Ah, there is a different repo for that named ngraph.graph to use alongside ngraph.path

You are correct. the createGraph comes from ngraph.graph:

So, using npm:

npm i ngraph.graph

and then

let createGraph = require('ngraph.graph');
let graph = createGraph();
