Fix "undefined" in charts

[jackiekazil]

In the Geo-schelling and urban growth models, I noticed that the charts said "undefined". I don't have time to look into this at the moment, so I'm dropping here just in case someone dose.

To recreate -- launch either model in the browser. I assume it is the same issue.

mesa versions that the requirements file in urban growth model was tied to -- mesa-1.1.1 mesa-geo-0.5.0

Thanks for reporting. This has been raised in projectmesa/mesa-viz-tornado#26 and projectmesa/mesa-examples#64 and is supposed to be fixed by projectmesa/mesa-viz-tornado#37. But I haven't tested it yet.

Tested and verified that it's indeed fixed, although the fix is not yet released to PyPI (as mentioned in projectmesa/mesa-viz-tornado#37 (comment)). To get the fix, users need to install mesa-viz-tornado from source:

pip install git+https://github.com/projectmesa/mesa-viz-tornado.git#egg=mesa-viz-tornado

I'll leave this issue open until it's released.

Fixed with mesa-viz-tornado v0.1.3 release.
