Looks great! Thanks for that!

Since you already have all the data: Would it be possible to add some charts?

Like Difficulty over time.
Or Hashrate over time.

Also nice to have would be number of transactions/day over time...

[EDIT] Where do you get the "Estimated Network Hashrate" from? http://fc.dontmine.me/accountdetails and https://featherpool.com/ show much higher hashrates.
