This is a spin-off from a question I answered for someone on the forum recently.
I thought it would make a great fill-in exercise for any of my IoT students who have a few minutes to spare towards the end of a session of my IoT Club.
Here's a screen-shot of a simple dashboard - I'm sure most people could improve it.

I'm using the API at... http://api.open-notify.org/iss-now.json to obtain the 'lat' & 'lon' of the ISS, then send these details to the worldmap node. I suggest you restrict the Trigger interval to 5-sec or more otherwise the server at open-notify might get a bit stressed. (The animation looks pretty good at 1-sec intervals.)
I hope someone finds this flow useful.
EDIT: Updated flow and screenshot with ISS icon.
