Project assignment

  • A project should have the following requirements:
    • The application should contain several visual widgets, each providing insights on a selection of dimensions of the original data
    • It is possible to use state-of-the-art charts (bar charts, line charts, etc.) and libraries (, vega, etc).
    • The final evaluation will take into account the implementation of a novel, original visualization to present the data in a creative, non-trivial way, using D3.js (see examples on Vast Challenge 2008 developed in class). You can refer to visualization techniques already present in the literature, by adapting or implementing part of the solution.
    • Interactivity should be implemented, providing toolbars, selections, and filters for the data.
    • The visual widget should interact among them, realizing a set of linked displays to browse the data across multiple dimensions
    • The project should be submitted as a Git repository
    • The project report should be submitted 4 days before the discussion and should discuss at least the following points:
      • Description of data and presentation of the pattern or model to communicate
      • design choices: colors, interactions, shapes, transformations)
      • state-of-art: similar tools or interfaces for the same problem
      • Detailed description of the visualization with a description of the interaction
      • use case example for an analytical task

The student may choose one of the following project proposals. She/he can also propose an additional topic. In this case, a project proposal should be submitted for approval, containing a description of the data, a sketch of the possible visualization, and the motivation for the project.

VAST Challenge 2023 :!: **new**

The project assignment for the exam consists of the realization of a web application addressing data and mini-challenges presented for the VAST challenge 2023 ( Each student may choose one of the mini-challenges to build a visual interface that answers the proposed questions (see the list on the corresponding page on the VAST website).
