PingGraph is a terminal based C program that continuously measures and visualizes the network latency (ping) to multiple hosts.
It displays a live bar graph in the console, tracks statistics and supports machine readable exports..

1. Pings each host once per interval or just once (--once).
2. Parses and extracts the latency from the system ping command.
3. Visualizes the latency using a color coded ASCII bar.
4. Tracks min / max / average latency and timeouts for each host.
5. Logs results to a file or exports as JSON/CSV on demand.
6. Displays a final summary if requested.

• Interactive or file based host input.
• Live bar graph with latency color codes.
• JSON output (--json).
• CSV export (--csv le>).
• Interval mode (--interval N) or limited rounds (--limit N).
• Summary view (--summary).
• Timeout tracking.
• ANSI color toggle (--no-color).
• Log to file with append support (--log-append).

• A C compiler (GCC or MSVC).
• POSIX compatible system or Windows.
• System ping command available in PATH.

Compile:

gcc main.c -o pinggraph

Run with interactive input:

./pinggraph

Run with host file:

./pinggraph --hosts hosts.txt --interval 5 --summary

Print as JSON:

./pinggraph --once --json

Export as CSV:

./pinggraph --once --hosts hosts.txt --csv results.csv

Simple plain text file, one host per line:

• Works best in a terminal that supports ANSI colors.
• For consistent results, run with administrator/root privileges.
• To stop the program during live execution, press Ctrl+C.
