margin-stream - streamgraph from margins

[danse]

This is the best starting point i found so far.

Since it is possible to have multiple tags on the same value, i should have a function to eliminate overlaps. This would be a function like [(Value, [Tag])] -> [(Value, Tag)] such that the sum of the input values is equal to the sum of the output values. The function should pick a tag, for example the tag with the biggest or smallest cumulated value before the function execution

$ exmargination-streamify margin.json

It would be nice to have it working from standard input if the file is not provided, because i might need preprocessing steps

$ exmargination-tags --first | exmargination-group --day | exmargination-streamify

exmargination-streamify would internally accept data in the form [(String, Float, Date)]. This could be the first visualisation supported by a new Vishnje https://github.com/danse/vishnje/issues/1

I imagine the following components:

• vishnje providing a lightweight framework
• A streamify library that gets a [(String, Float, Date)] and produces a stream graph using Vishnje
• exmargination-streamify that parses a Margin file and uses Streamify
