  The creation of cartoon-based stories (comics) requires a lot of creativity
and hard work for naive users. We observe that single-panel cartoons are the
building blocks of any comic story. To develop a strong comic story, it is
critical to obtain visually valid single panels. In this work, we have
developed a methodology to guarantee the placement of characters to obtain a
valid cartoon frame based on the methods used by professional cartoonists.
Using this methodology, we have developed a web-based system to create
single-panel cartoons from a given set of character images. We have made this
system available in GitHub as open-source so that this basic single-panel
cartoon can be used as infrastructure to develop more complex structures. Our
web-based system for single-panel cartoons can be viewed at
