Data graph

In preparation for the check-in of Innopolis University applicants at InnoBootCamp 2023, we collected a data graph showing the relationship between participants, their answers to the questions from the feed. We have also included the result of the applicant distribution by room in this graph.

The graph is presented as three files:

• participants.json - a list of participants.
• fields.json - a list of single-choice questions.
• answers.json - a list of answers to the questions.

Below you will find a description of each node stored in the data graph.
