[CLJS] Replacement for byte-array in commits->matrix for GitHub heatmap?

[f6m6]

Hi there - thanks for the amazing tools. 😄 I've got a bar graph working in my reagent project and am now looking at adding the GitHub-commit style visualisation.

1. When it comes to the commits->matrix function I'm stuck as byte-array doesn't exist in ClojureScript. I tried binding mat to ((nd/ndarray :int32 (repeat (* 7 weeks) 0) [7 weeks]) but it didn't make any difference - I get a weird error down the line:

Can I drop in a replacement for byte-array? I used int64 because int32 is not available in the CLJS version of ndarray.

2. I've also tried binding commits to my raw data in the actual example hm-github.clj (so running on Clojure, not ClojureScript) and it actually doesn't work, saying CompilerException java.lang.IllegalArgumentException: Value out of range for byte: 228, compiling:(/Users/farhan/code/geom/geom-viz/babel/examples/hm-github.clj:57:1) - I definitely never had 228 commits in a day! But I guess the use of a byte array assumes a certain number of commits per day? Maybe if you can talk me through generally what's happening in this code I can fix it myself...

It's worth mentioning that my timestamp data is from another source, not GitHub commits. Here is the data as a list:

Thanks for any help you can give.

Alternatively, could you maybe show me the code for this stuff on the thi.ng homepage?
