The maturality and extensive graphical abilities of R and its packages make R an excellent choice for professional data visualisation. This talk focuses on interactive spatial visualization and illustrates two different approaches with case studies based on open crime data in UK (Home Office, 2014).
Previous work has shown that it is possible to combine the functionality in packages ggmap, ggplot2, shiny and shinyapps for crime data visualization in the form of a web application named 'CrimeMap' (Chow, 2013). The web application is user-friendly and highly customizable. It allows users to create and customize spatial visualization in a few clicks without prior knowledge in R (figure 1). Moreover, shiny automatcially adjusts the best application layout for desktop computers, tablets and smartphones.
