While stippling is often regarded as an illustrative method, we argue that it is worth investigating its suitability for the visualization domain. For this purpose, we generalize the Linde-Buzo-Gray stippling algorithm for information visualization purposes to encode continuous and discrete 2D data. Our proposed modifications provide more control over the resulting distribution of stipples for encoding additional information into the representation, such as contours. We show different approaches to depict contours in stipple drawings based on locally adjusting the stipple distribution. Combining stipple-based gradients and contours allows for simultaneous assessment of the overall structure of the data while preserving important local details. We discuss the applicability of our technique using datasets from different domains and conduct observation-validating studies to assess the perception of stippled representations.</dcterms:abstract> <dc:creator>Görtler, Jochen</dc:creator> <dcterms:issued>2019-06-01</dcterms:issued> <dc:contributor>Görtler, Jochen</dc:contributor> <dc:contributor>Schulz, Christoph</dc:contributor> <dspace:isPartOfCollection rdf:resource=""/> <dcterms:hasPart rdf:resource=""/> </rdf:Description> </rdf:RDF>
