We present initial results of a quantitative analysis of how developers
layout the visualisations in their multiple view systems. Many developers
create multiple view systems and the technique is commonly
used by the visualisation community. Each visualisation shows data
in a different way, and often user interaction is coordinated between
the views. But it is not always clear to know how many views a
developer should use, or what would be the best layout. We extract
images of visualisation tools, across TVCG journal, conference,
posters and workshop papers 2012-2018 to analyse the quantity and
layout of the views in these visualisation systems. Focusing on view
juxtaposition, we code the layout of 491 images and analyse view
topology in juxtaposed views. Our analysis acts as a starting point
to help designers create better visualisations, acts as a taxonomy of
visualisation layouts, and provides a quantitative analysis of how
many views developers have used in their visualisation systems.
