You can use macros in Stata to help create the exact graph you want. One of the uses for macros is to take a text paragraph and add it to your graph as you would like.

To generate this graph in Stata, use the following commands:
. sysuse auto, clear
. local lines "The development of Linux is one of the most prominent examples of free and open source software collaboration; typically all the underlying source code can be used, freely modified, and redistributed, both commercially and non-commercially, by anyone under licensessuch as the GNU General Public License. Typically Linux is packaged in a format known as a Linux distribution for desktop and server use."
. forvalues i = 1/11 {
2. local line : piece `i' 40 of "`lines'"
3. local text `"`text' "`line'""'
4. }
. graph bar price, bargap(-30) over(foreign) note(`text', margin(large) justification(left))
