Accumulative Cumulative frequency plot

I have the following data:

data = 
 {{0, 0}, {20, 1.4}, {25, 9.8}, {30, 32.2}, {35, 38.2}, {40, 15.6}, {45, 2.7}, {50, 0.1}};

where the second coordinates are frequencies measured as percent of total (adding, therefore, to $100$). I would like to getproduce a accumulativecumulative frequency plot of this data. What would be the neatest way to do so?

EDIT: Yes, I meant accumulative frequency, thanks for correcting me!
