6. A pie chart shows a certain percentage for
each variable , where each variable added up
equals 100%. The bigger the slice is the more
percentage of the whole thing is made up of
that part or slice. It can be used to show how
much something is liked(the song) compared
to other things(all songs played on MTV
total request live). Each song represents a
certain percentage of it standing weeks at
number one

8. A scatter plot represents a single data point
with one mark (point) for every data point a
visual distribution of the data can be seen.
A scatter plot show positive or negative
correlation.
We chose to do a scatterplot for the comic
book orders because the Est. sales have a
positive correlation but the numbers are very
far apart. A scatter plot is used to show a
cluster, not the distinct point of the value.
