Just made a tool to estimate and show the XMR transaction speed

https://github.com/Lafudoci/XMR-ETA

This python script sorts the information from xmrchain and estimate the tx confirm time. And uploads them to the thingspeak database.

Finally the information can be visualized on webpage like this:

Since I has just started learning python and it's my first project for monero. Most of the logic of estimation method is from my observation not the actual math from monero algorithm. For now the estimation is based on size. No fees order yet. But most of the time it estimates the conservative confirm time well for normal wallet transaction with normal fee. Still learning how to refine the code and understanding the tx process behind the monero. Any suggestion is welcome so that I or we can improve it.

update: efficiency rating presents the block size demand is up (>100%) or down (<100%), however thanks to zentropicmaximillist's advice, will find another way to to visualize it to make it easier to understand.
