Plotting graph from Text file using R

I am using an NS3 based simulator called NDNsim. I can generate certain trace files that can be used to analyze performance, etc. However I need to visualize the data generated.

I am a complete Novice with R, and would like a way to visualize. Here is how the output looks from which I would to plot. Any help is appreciated.

It's pretty difficult to know what you're looking for, since you have almost 50,000 measurements across 9 variables. Here's one way of getting a lot of that information on the screen:

df <- read.table(paste0("https://gist.githubusercontent.com/wuodland/",
                        "9b2c76650ea37459f869c59d5f5f76ea/raw/",
                        "6131919c105c95f8ba6967457663b9c37779756a/rate.txt"),
                 header = TRUE)

library(ggplot2)

ggplot(df, aes(x = Time, y = Kilobytes, color = Type)) + 
  geom_line() + 
  facet_wrap(~FaceDescr)
