But maybe it could be a function?
base_tiger_url(year, layer) = "https://www2.census.gov/geo/tiger/TIGER$(year)/$(layer)/"which would neatly remove the Format.jl dependency as well.

what are the three different things here? julia name, tiger name, description? We should describe this explicitly

not quite - seems it saves as zip files? Shapefile.jl has zip support via ZipFile.jl but it's a bit dicey.

I made a new PR #7 with this code and some additions from my end, but can't target it to this branch. |
|
See TheCedarPrince#1 for the diff if interested, feel free to merge that there as well and I can close #7 here |

Hey @asinghvi17,
Finally, after a year in the making (more like 3 hours), we have downloading somewhat built out as a first draft for TigerLine.jl! This adds a few useful constants and one new function called
download_tiger. Here is what it covers:Not sure how to add tests to this, but otherwise, excited to get this functionality made finally!
