### Empirical Data Plot

I wish to make a plot of N vs Time where $N=$ # of edges in a graph.
i.e. i want to make an empirical estimate of the time complexity it takes to compute certain things about a graph based on its number of edges.

so i guess i'm wanting to know how i can plot these data points in sage and find a polynomial that best fits?

i.e.

N = [(16,28,59,120)]

T = [(0.135,0.523,7.36,248)] --where time is measured in seconds

i'm a beginner so any help will be much appreciated.
