Terminal Weather Data Visualizer

A C++ terminal application to read, filter, and visualize weather data from a CSV file using candlestick-style ASCII plots.

Features

• CSV Parsing: Reads weather data from a CSV file with dynamic detection of country codes from headers.
• Candlestick Visualization: Displays temperature trends using red/green terminal plots similar to stock market charts.
• Menu-Driven Interface:
  • 1: Print Help
  • 2: List Country Codes
  • 3: Print Candlestick Data (by day/month/year)
  • 4: Plot Candlestick Data
  • 5: Filter and Plot Data by Date Range

How It Works

1. The app loads data from a data.csv file.
2. You can select country codes and filter by time (day, month, year).
3. Plots are rendered in terminal using ASCII characters (|, -, etc.).
4. Red/green colors indicate temperature drop or rise compared to the previous point.

Requirements

• C++17 or above
• Standard C++ libraries (no external dependencies)
• A terminal that supports ANSI color codes (for red/green visualization)
