Making quick charts in mysql takes advantage of the visual math cores in our brains.
Using the rpad function
allows us to do so in the mysql shell, e..g.
mysql> select value, rpad('', count(*), '#') from mail1_161
where oid = '.1.3.6.1.4.1.9600.1.1.5.1.5.1.48' and value > 0
group by value order by value desc;
+-------+-------------------------+
| value | rpad('', count(*), '#') |
