Abstract

Heat maps are a commonplace tool to communicate geolocated information. There are a lot of features in a heat map's visualization that are able to be perceived differently. Parameters such as color and threshold can influence how the data is understood. In the specific context of visualizing restaurant density, we conducted a mixed methods study to measure how these two parameters can affect a user's perception of data quality. We present preliminary results of interviews, and an online survey.
