Is there a service for determining the shortest path to a point (or several points)?

Question

Google

Tell me if there is a service for determining the shortest travel time to a point (or several points), taking into account movement by public transport, displaying the results in the form of a spectrogram - the closer, the redder, the farther, the bluer. Any other adequate convenient way to display results will do.
This is necessary for a convenient choice of the region to search for an apartment on cyan with the shortest travel time to work. As you know, the shortest distance does not always guarantee the shortest time.

Answer 1

Of course
, Yandex, Google and 2gis
have hardly any spectrograms there, only JSON
