added streaming example using bokeh server and nyc_taxi.csv

[brendancol]

To run example:

cd examples
bokeh serve stream.py --show

It will take a little bit for the nyc taxi to load into memory. From there, you will need to pan or zoom once to kick off streaming.

Things that would make this example better:

• start streaming immediately instead of need to pan/zoom to start
• add time slider instead of text and allow user to change

Looks great to me! Nice, simple code, and a cool demo.

Any idea why the data is being clipped across the top of Manhattan in that image? There are data points above that in the dataset...

I wonder if I'm working with an older nyc_taxi.csv that got cut off. When I run wc nyc_taxi.csv, I get 10679308 lines in the file. Does that sound correct?

[jbednar]

I get 11842095, so yes, probably your nyc_taxi.csv was created using too-tight a bounding box.

That shouldn't affect the code, which I'm happy for you to merge whenever you are ready.
