Copious paper sketches were produced to explore ways to combine information, function, visual form and story within the visualisation, with the aim to inform and inspire users. The hand-drawn diagrams were then digitalised using Sketch. Rapid prototyping in Sketch enabled me to experiment on the utility of the design.
Maps were selected to be the basis of the visualisation due to their strong ability to communicate geographical data. A choropleth map was used to distinguish the difference in price and number of listings. For example, the denser the listings, the darker the shade. Separate bar charts and text complimented the map to provide further detail.
The design in Sketch became a blueprint for an interactive data visualisation using Processing. Airbnb listing data was aggregated by borough and plot on a map. Users control the degree of focus by filtering factors (price, crime rate, room types) with keyboard or mouse interaction. These additional factors provide users with a way to explore and combine the data with ease.
Here is a video to show the data visualisation with mouse interaction.
