display gets corrupted on bogus data #4
Description
Reopen goerli/netstats-server#13 by @veox
Most commonly visible on bar-graphs for block time, difficulty, transaction count...
The most common cause is someone accidentally connecting a node from network X to dashboard of network Y; but this could also happen due to malice.
In general, the dashboard is overly trusting in accepting the data fed to it as correct, and does not gracefully handle conflicts.
