better charts

What people say:

Alright : The propositions are more oriented on the readability of the graphs. I'm a young researcher, and i've been triggered (like a good karen) by the lack of ease into data reading that i'm not used too :p

My main concern is about the typing speed graph : -Add an explanation to what operation the "smoothness" does to the data : It will help people to understand how to read this chart. I guess it means the y values with n neighbours, depending on the smoothness value, but i feel like something is off : when you smooth at max value, the max typing speed drops from 37 to 12.2 wpm. So you should maybe warn that smoothed values are not real ones and that the axis graduation is not representative. Then, mention that the smoothness is just for better learning curve visualization. -Add Y axis scale for error and key number on the left.

For key frequency histogram -Add a Y axis scale and/or the value on each bar : there is absolutely no Y values indications, that makes them useless. We have no scale to get an idea of the values.

For key frequency heatmap -Add a legend : i can not understand what is displayed here. It seems like it is error vs good strike. -Add a scale : If red is mistakes and green good strike, I think I make less mistakes than good strike, so why are both keys the same size ? Maybe you should uniform the scale between max error and max good.

I hope this will help you to improve the readability of the metrics you display.

Overall the website is really good looking and you made a great job ! I'm really enjoying my experience with it ! So thanks a lot for your hard work !
