These charts from [CalRecyle's used oil LCA](http://uo-lca.github.io/dist/#/home/fragment-lcia) are super cool:

and also a great way to show the effect of displaced impact - instead of those awful stacked bar charts where some sections are below the axis and some are above.

(I'm a coauthor on the [paper this is from](http://pubs.rsc.org/-/content/articlehtml/2014/gc/c4gc01124d) so I feel partly responsible...)

It might need a way to tag the processes belonging to life cycle stages. Alternatively could use the levels from the bullseye chart or named intermediate processes.
Add a waterfall chart?

Getting better - thanks to finding the original code, thankfully also written for d3, [here](https://github.com/uo-lca/FrontEnd/)

With a bit of lcopt styling too:

code here: https://gist.github.com/username_0/5509518c138d59f1c40203d1f542da85

Next: need to figure out how to pass it an lcopt data structure and include it in the results section

Here are some examples.

The waterfall chart is implemented:

The tree can now have green branches:

And the charts can now go negative:
