OverviewOverview

The aim is to create a software providing The aim is to create a software providing high-level plots and analysis of PingER high-level plots and analysis of PingER historical data, which will be useful for historical data, which will be useful for executives.executives.

The plots must therefore be simple to The plots must therefore be simple to interpret while providing all the necessary interpret while providing all the necessary information about trends in the data.information about trends in the data.
