Travis CI failed because plotly won't authenticate. I ran the http.server module locally and saw plotly working, so I didn't do this originally. I signed up for some credentials and initialized my plotly .config file. I notice that in your authenticate_plotly.py script first imports plotly and then os, before calling the os.environ dictionary. For me, my credentials don't get written to the os.environ mapping. I can just plug in my credentials directly, but this isn't good practice. |

Thanks for doing this. I'm trying to fix the build now. |

Plotly had breaking changes. |

Took me a long time to get read to add altair examples. I ended up using the ones proposed by @roycoding, but I added both of you as coauthors to the commits. Thanks for your help. |

Hi Tim,
While researching the Altair library, I came across your plot comparison website. On it, you mention that you wanted additional examples (including Altair). Since I needed to learn Altair anyways, I figured I would contribute some plots (hence - this pull request was born).
A few notes:
I got everything working correctly. However, I did not use a Conda environment as stated in your ReadMe.md. I instead used venv + python3.7.2. All the scripts, notebooks and web server seemed to work just fine (on my end).
Getting Altair to work with Jupyter Notebook is a bit troublesome. I had to downgrade the vega package. It seems that the latest vega package (which contains both vega 3 and vega3-lite), is made to work with altair3 (not yet released). Downgrading to vega==1.3.0 solved the issue. See: NoSuchEntryPoint: No 'notebook' entry point found in group 'altair.vegalite.v2.renderer' vega/altair#1114 for details.
In the plots, I tried to balance simplicity with features. For the earlier plots (bar-chart, simple-histogram), I use terse code. For more sophisticated ones, I add more calls to show off Altair's features.
There were a few plots that I could not easily generate: the regression and line fitting plots, and the KDE plot. Much like your regression plots (with plotly?), Altair does not do this out of the box easily. I didn't have the time to work them out.
