## Overview

Tailspin SpaceGame Web is an ASP.NET MVC leaderboard and player-profile viewer. A browser request reaches HomeController: the leaderboard action filters, sorts, and pages scores, fetches each score’s profile, and returns a view model; the profile action fetches one profile and returns its view. Startup wires these requests to JSON-backed in-memory repositories. The graph reflects the sampled controller, repository, and startup code; view rendering is represented by the controller’s View results, while unsampled view details are not inferred.

Main entry points: [`Tailspin.SpaceGame.Web/Controllers/HomeController.cs`](https://github.com/sdk2575/mslearn-tailspin-spacegame-web/blob/main/Tailspin.SpaceGame.Web/Controllers/HomeController.cs) (Home controller), [`Tailspin.SpaceGame.Web/Startup.cs`](https://github.com/sdk2575/mslearn-tailspin-spacegame-web/blob/main/Tailspin.SpaceGame.Web/Startup.cs) (Web startup), [`Tailspin.SpaceGame.Web/IDocumentDBRepository.cs`](https://github.com/sdk2575/mslearn-tailspin-spacegame-web/blob/main/Tailspin.SpaceGame.Web/IDocumentDBRepository.cs) (Repository contract), [`Tailspin.SpaceGame.Web/Models/Model.cs`](https://github.com/sdk2575/mslearn-tailspin-spacegame-web/blob/main/Tailspin.SpaceGame.Web/Models/Model.cs) (Base data model)
