Hi I found this great example:
I am still learning and I am not sure how to read the nested functions for x.
I.e. when Mike Passes
x: d => d.state,
x = (d, i) => i I am not quite sure how to understand it.
And later this map is applied here:
const X = d3.map(data, x);
I thought this should be the same as applying
How would I write this directly, or how can I understand what this nesting does?
Thanks a lot for any tips and help in advance!
