README
sdr-heatmap 
I'm using this as an opportunity to learn Rust.
A tool to visualize files generated by rtl_power. Inspired by heatmap.py. It aims to provide better speed than heatmap.py, while keeping the same image format. Another similar tool is rtl-gopow, but it produces a different (IMO inferior) image than heatmap.py.
Installation
cargo install sdr-heatmap (from crates.io)
Speed (WIP) (v0.1.2)
