Visualize percent of people within distance I hope that's not a too trivial a question for this site. 
I'd like to graphically represent the percentage of users that are x miles away from a certain point. 
E.g. 
60% live within 5 miles, 70 within 10, 80 within 15 miles. Is there a easily understandable graph to visualize that or should I present this information in textual information?
 A: You may be looking for a straightforward gains chart. Just plot the cumulative percentage on the vertical axis against the distance on the horizontal axis. Add an initial zero to both series for a useful starting point, and potentially something corresponding to 100%, i.e., the distance of the user that lives farthest away. (If that is unavailable or would make for an unreadable chart, then just leave this off and only go to a cumulative percentage that covers "enough" users.) In R:
cumulative.percentage <- c(0,60,70,80,100)
distance <- c(0,5,10,15,25)
plot(distance,cumulative.percentage,type="o",pch=19)


A: The simplest solution is to collapse your individual datapoints into ranges. 
For example:


*

*0-5 miles

*6-10 miles

*11-15 miles

*16-20 miles

*21 + miles


You might end up with 6 people who end up in the 0-5 miles range, 10 people who end up in the 6-10 miles range, and so forth. The important thing is to make sure that your ranges are mutually exclusive. This means that no person should fall into more than one category. 
Once you have done that, it is quite easy to visualize your data using a simple pie chart.
