This dashboard visualizes synthetic weather data for six cities, presenting monthly temperature and pressure trends through line, bar, and stacked area charts. The charts are created with Chart.js on a Canvas renderer. Interactive buttons let users highlight a specific city, updating the line chart, bar chart, and scatter plot attributes. The dashboard also includes dropdown menus for year and city selection, enabling the linked charts to update accordingly. The code defines sample data directly and uses Chart.js’s API to manage chart instances and datasets.
