Community Support

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.
