Optimisation
One server snapshot for all users.
Data is refreshed every hour on the server side. Changing the parameter or downloading the PNG uses the same dataset, so users don't multiply requests to the external API.

Temperature map
A ready 4K graphic of Poland with circles over the largest cities per province. The circle colour shows the selected parameter; red border marks the highest value, blue the lowest. Nearby circles are positioned so they don't overlap; for wind a direction arrow appears next to each circle.

Data honesty
This is a point map, not an official warning.
The circles show conditions for selected cities. Values between cities may differ, so for safety decisions always check local weather notices and the current forecast.
