This is a simple pie chart showing the data type 'text-data'.
When you use this data type with pie charts, the first entry in each record
(a label) is ignored; the sum of all the second entries equals the relative
size of the first segment, the sum of the third entries is the second segment,
etc. So this pie has 4 segments, of relative size 250, 200, 350, and 200.
</p><p>
Data type 'data-data' is similar, except the first two entries in each
record (label and X value for other plot types) is ignored.
