Preliminary graphs

Visualizing the Data Static graphs

Plotting usage over time in one day, using different colors to represent upload/dowload averages and maximums of both primary and secondary providers

Plotting usage over year long time Plotting usage of many days in the same 24 hour

time span Comparing boxplots of the data usage for different

days in the week

Advanced Graphics Animated Graphs

Plotting usageover a two day timeperiod, where the area under the line fills over time

Interactive Graphs Allow user to set the day and time of day and

then show the average incoming and outgoing data usage, and the maximum incomingand outgoing
