A BibTeX entry for LaTeX users is
app is based on an
package that I have developed called eulerr. It generates
area-proportional euler diagrams using some rather groovy algorithms
and optimization routines written in
are generalized venn diagrams for which the requirement that all
intersections be present is relaxed. They are constructed from
a specification of set relationships but may sometimes fail
to display these appropriately. For instance, try giving the
app the specification
A = 5, B = 3, C = 1, A&B = 2, AB&C = 2
to see what I mean.
When this happens, eulerr tries to give an indication of how badly the diagram fits the data through the metrics stress and diag error . The latter of these show the largest difference in percentage points between the specification of any one set combination and its resulting fit. It is the maximum value of region error , which is given for each combination. This metric has been adopted from a paper by Micallef and Peter Rodgers. Stress is more difficult to explain, but I advise the interested reader to read Leland Wilkinson's excellent paper for a proper brief.
I have listed some links on the right if you are keen on learning more about eulerr, perhaps even to contribute to its development. Finally, I owe a great deal to the aforementioned Wilkinson as well as Ben Frederickson whose work eulerr is built upon.
Fixed a bug that causes buggy input handling in new versions of shiny. (Thanks Sparkleunicorn9)
Migrated to http://eulerr.co
Added option to set pointsize (mostly for fonts).
Added settings for height and width when downloading plots.
Added the option to supply a seed to enable reproducible layouts
