Dependencies

Hi,

I am trying to use your library (with THREE.js).

I tried to run the example javascript code inside an HTML file with the line:

<script src="https://d3js.org/d3-contour.v1.min.js"></script>

At the line:
var contours = d3.contours()
.size([n, m])
.thresholds(d3.range(2, 21).map(p => Math.pow(2, p)))
(values);

I got the error message: "TypeError: d3.range is not a function".

I guess I need to link another library?

Yes in that case you would need to add <script src="https://d3js.org/d3-array.v2.min.js"></script>

We should edit the README and replace d3.range by native JS:
Array.from({ length: 19 }, (_, i) => Math.pow(2, i + 2))

Thanks very much.

It works now when I link in the d3-array.v2.min.js file.

I managed to make a mistake when updating README: 8b837a9
