abstract = "Proportional symbol maps are an often used tool to aid
cartographers and geo-science professionals to visualize data
associated with events (e.g., earthquakes) or geo-positioned
statistical data (e.g., population). At specific locations,
symbols are placed and scaled so that their areas become
proportional to the magnitudes of the events or data. Recent work
approaches the problem of drawing these symbols algorithmically
and defines metrics to be optimized to attain different kinds of
drawings. We focus specifically on optimizing the visualization of
physically realizable drawings of opaque disks by maximizing the
sum of the visible borders of such disks. As this problem has been
proven to be NP-hard, we provide an integer programming model for
its solution along with decomposition techniques designed to
decrease the size of input instances. We present computational
experiments to assess the performance of our model as well as the
effectiveness of our decomposition techniques. .",
