This graph shows the history of the code for the Time Map iPhone application from the beginning of the project to the 1.0.0 release. 205 checkins produced about 8000 lines of code (120 printed pages) in three months. The data for the graph was generated by extracting the source control log messages and counting the number of lines of code after every checkin.

(The timestamps on the checkins are offset by several hours. I had not noticed for about eight months that the server wasn't running the NTP daemon.)
