## Overview

This is a FastAPI weather dashboard: a user opens the overview, selects a station and weather parameter, and the browser requests chart data and statistics for display. The API controller fetches observations from DMI and formats results; the page also exposes station and parameter choices. Source excerpts establish the main routing, fetch, and formatting relationships. The README is empty, and unsampled template and styling details are not inferred.

Main entry points: [`app/controllers/weather_controller.py`](https://github.com/akanext/dmi-weather-app/blob/main/app/controllers/weather_controller.py) (Weather operations), [`app/routers/weather_router.py`](https://github.com/akanext/dmi-weather-app/blob/main/app/routers/weather_router.py) (Weather API routes), [`main.py`](https://github.com/akanext/dmi-weather-app/blob/main/main.py) (FastAPI application), [`app/routers/views_router.py`](https://github.com/akanext/dmi-weather-app/blob/main/app/routers/views_router.py) (Overview route)
