Show HN: Realtime Ethereum gas fee chart

After struggling with timing ethereum gas fees for a while, I decided to make a graph that shows historical gas fees as well as realtime fees. That way I could gauge whether or not the current gas fee was reasonable based on past fee data. It's called blockgas.io, and a few of my friends have found it useful so I decided to drop it here as well. Please let me know what you think, and if you want me to add anything to it.
