This dashboard visualizes monthly weather data, including temperature and pressure, for nine cities. Users select a city from a dropdown to update line and bar charts built with Chart.js, each displaying a distinct dataset. A stacked area chart and a scatter plot further compare temperature trends and the temperature-pressure relationship across all cities. The interface also includes a Leaflet map with popup markers showing city temperatures. Charts use mock data, while the map is rendered with OpenStreetMap tiles and the Leaflet API.
