Abstract
We present WhaleVis—an interactive visualization and analysis dashboard for the IWC catch database, with the goal to facilitate understanding whaling events and the resulting changes in whale population distribution over the years when whaling was rampant, and prioritize management and conservation efforts for populations under the threat of extinction today. We first canvassed a sample of questions that can be answered using the catch database, and then designed and implemented our dashboard to facilitate answering these questions. Our tool is implemented using the Observable4 notebook environment, which ensures data and code transparency and facilitates collaborative analysis. We provide a set of visualizations of the catch data, which enable both overviewing the data and filtering down to attributes of interest, using intuitive interactions with the visualization itself. In addition to visualizations and the ability to extract selected portions of the database in comma-delimited (.csv) format, we also introduce users to new perspectives of the data. Notably, we plan to use the information about the timeline and routes of the expeditions contained in the database to (1) model the data in terms of a network graph representation, where the nodes represent locations of whale sightings, and the edges represent whaling expedition routes, and (2) use the network graph representation to plot population maps normalized by search effort i.e. catch-per-unit-effort (CPUE). This would further open up new avenues for performing graph analysis on the data. We demonstrate the use of our dashboard through three example use cases.
