First, you have to install Rust and Cargo (the build tool for Rust).
Follow the instructions at the Rust website (https://www.rust-lang.org/tools/install).
Make sure you add the ~/.cargo/bin directory to your Path.
Then download this repository somewhere onto your computer.
Unzip it and navigate to it, so that the directory containing Cargo.toml is your current working directory.
Run cargo run. This should automatically install dependencies, build, and run the project.
For an example usage, download this launch file, then select it as the source and example/packet.h as the packet format.
Left-click+Drag in the plot window to box zoom. To reset the zoom, double-click in the plot window.
Loading in all the rows from the launch file into the graph makes the application laggy. To mitigate this, increase the sampling in the plot tab to reduce the number of data points plotted.
