App was developed as part of the hackaton organized by Futurice in Helsinki. I choose the HSL track and developed a tool that answers the following question:
If I am in this stop, what are all the places I can go if I just go one stop further?
For it I used shiny, which I was already familiar with, and learned GraphQL to connect to the API to fetch the data. Then leaflet is used for the mapping and mapbox for the special themed map.
