Summary and Overview; Part II
1.2.1
he ten chapters in Part II are concerned with principles of data visualization. First
there is an historical overview by Michael Friendly, the custodian of the Internet
Gallery of Data Visualization, outlining the developments in graphical displays over
the last few hundred years and including many fine examples.
In the next chapter Antony Unwin discusses some of the guidelines for the prepa-
ration of sound and attractive data graphics. he question mark in the chapter title
sums it up well: whatever principles or recommendations are followed, the success
of a graphic is a matter of taste; there are no fixed rules.
he importance of sotware for producing graphics is incontrovertible. Paul Mur-
rell in his chapter summarizes the requirements for producing accurate and exact
static graphics. He emphasizes both the need for flexibility in customizing standard
plots and the need for tools that permit the drawing of new plot types.
Structure in data maybe represented bymathematical graphs. George Michailidis
pursues this idea in his chapter and shows how this leads to another class of graphic
displays associated with multivariate analysis methods.
