To view my examples, view the "aaaindex.htm" file in an IE browser.
                               ^^^^^^^^^^^^
I recommend IE rather than netscape because netscape does not
support the html alt= flyover text, which many examples uses.

Hopefully these examples show that sas graphics software can do 
"Just about anything", and the sas code will provide a good
starting-point for sas users who are wanting to create similar
graphics.  Some other graphics software might be easier to use
than sas, but sas graphics gives you the flexibility and power
to produce almost *any* kind of custom graphics you want - and
this can be done programmatically so the production of new/updated
graphics can be easily generalized and automated (whereas most 
other 'easy-to-use' graphics software only provide a GUI-based
interfaces and you have to keep manually re-creating their graphics
over and over.)

These examples were all created by Robert Allison, as test cases
to test SAS software.  For most of these examples, a nice-looking
non-sas graphic was identified in a webpage, paper, magazine,
or other public forum, and Robert then wrote sas code to 
produce a similar (or hopefully better!) sas version of the
same graphic.  And, a few of the examples are totally 
original (not based on any previously-existing graphic).

In addition to showing the sas graphics capabilities, these 
examples also make heavy use of sas "ods html" capability,
which provides chart-tip flyover text, drilldowns, hotspots,
3d borders, and other ods style capabilities.  Note that I've
set up many of the drilldowns such that they tie in to the
actual/real web pages out on the web.

These examples were created using v9 sas on a Windows PC.
They should most all be able to run using v8.2 and higher sas,
and they should run ok on Unix also (unix doesn't have all
the fonts, such as "arial", therefore you might have to 
try changing the fonts and font sizes to get them to look
good on unix).  Also, if you leave out the "ods html" stuff,
and the html= drilldown stuff, you should be able to get 
most of the graphs and maps to run in v6 sas as well :)

All of the code for these examples was written by Robert Allison.
These examples (intentionally) look very much like graphics that our
customers and competitors have, but the examples and sas code
used here were totally written from scratch (ie, no code was 
"borrowed" or "stolen" - it was all written totally from
scratch by Robert Allison).

Be aware that the data used in these examples should all be
considered as contrived/non-accurate data.  In most cases
the values were just 'eyeballed' from the original graph,
and in some cases the data are just totally random fabrications.
The examples were designed to look "plausibly real", but please
do not rely on the data values as being correct!

Updates:

 (none so far :)
