docs: Add ITP's TransitExplorer tool to visualization category

[markjd84]

We haven't even sorted a domain name yet, but there is an article explaining TransitExplorer and I'll put a gif below. If anyone wants to try it, or more info, give me a shout :)

...oop the GIF is too big for GH, but you can see it on twitter

Thanks!

@markjd84 Thanks for sharing this! Could you clarify if this tool is free to use?

[markjd84]

It's not, sorry, though we haven't got fixed pricing in place yet. Anyone who wants to try it is welcome to drop me a line!

edit: contact, if useful: [email protected] or through GH

@markjd84 Ok - I'm going to hold off merging this for now until you've got a permanent webpage and pricing is determined. Most of the resources on this list are free and open-source, so I just want to make sure that those that aren't are appropriately labeled to avoid confusion. This might entail a new section in the list (similar to "Native Apps (closed source)").

One option would be to add another community-maintained list: https://github.com/CUTR-at-USF/awesome-transit#community-maintained-lists

...that's "Entities providing GTFS analysis services" or something similar, and capture commercial services like yours there.

[markjd84]

Ok, no problem, thanks for info!
