This fork of a weather data dashboard displays monthly temperature and pressure statistics for Bangalore, Vancouver, and San Francisco. It presents the data through multiple Chart.js canvas renderings: a line chart for temperatures, a bar chart for pressure readings, a stacked area chart, and a scatter plot correlating temperature against pressure. Users can switch between the three cities using header buttons, which dynamically update each chart's datasets and highlight the selected city while dimming the others. The code uses the Chart.js library and its Chart constructor to build all visualizations.
