A bubble chart draws bubbles for each point in a series. The chart expects three values per bubble: the domain (commonly the X-axis)
...
value,
...
the
...
range
...
(commonly
...
the
...
y-axis)
...
value,
...
and
...
a
...
third
...
value
...
(the
...
Z
...
value)
...
that
...
determines
...
the
...
size
...
of
...
the
...
bubble
...
to
...
draw
...
around
...
the
...
point.
...
The
...
size
...
of
...
the
...
bubble
...
is
...
derived
...
from
...
an
...
algorithm
...
that
...
takes
...
the
...
Z
...
value,
...
divides
...
it
...
by
...
the
...
maximum
...
Z
...
value
...
in
...
the
...
dataset,
...
then
...
multiplies
...
that
...
number
...
by
...
the
...
max-bubble-size
...
property
...
value.
