You can see the visualisation of snapshot results on the profiles of your team members. The visualisation will show you the evolution a person went through and how they compare to the rest of their team or the company average.
Note: If you're a platform admin, you will be able to see snapshot results of people outside your team as well.
As a team lead you can find a 'Snapshots' tab on your team member's profile page. Accessing this tab will show you the results plotted on a graph, divided per question. On that graph you will see the historical evolution of your team member, your team(s) and the organisation.
You can click on 'Read feedback on this question' to find out the motivation behind every score.
