Hi folks, I am new and looking for a tool to generate a USA map.
I came across this Texas map example. I would like to do some
research and generate a similar map with my own data. Can anyone tell
me how to access this two data ( us_counties, unemployment).
It looks the head() function does not work
Thanks in advance
Jason
from bokeh.sampledata import us_counties, unemployment
Hi Jason,
I apologize but it's been awhile, so I don't recall the data format of that very well. It was thrown together fairly quickly to get that demo showing. A little poking reveals that
bokeh.sampledata.us_counties.data
is a plain python dict. It is indexed by some tuple of id's for each county (I definitely don't remember what the id's are from). For each county-tuple-id is another dict that has the data for each county. It looks like this:
In [31]: us_counties.data[(5,51)].keys()
Out[31]: dict_keys(['lats', 'name', 'lons', 'state'])
So for every county, there is a name, a state and two lists, one for latitudes, and one for longitudes.
I hope that is enough info to get you going.
Thanks,
Bryan

Hi Bryan,
Thank you so much for the information so that I could convert the dict as Dataframe.

No problem, and I agree a dataframe is a much better and simpler format for the data. The reason we kept it as a dict is that we are trying to minimize the external dependencies. Right now pandas is optional, and only required if you want to use bokeh.charts API.
