Long ago, I interviewed for a job at a company that wrote race car monitoring systems (ie displaying graphical real-time data about car & engine state and conditions). They wanted to know how I would go about developing such a system. My young green self gave some half-arsed answer and I didn't get the job (sadly. The perks were magnificent).

Looking back and knowing what I know now (having written a basic ECS mechanism for learning), I think ECS would work well as a guiding pattern. There's basically a fixed number of entities and components, and the systems are not hugely complex. Wire it up with a data input layer and a graphical output layer, and it would be a great fit.
