Each point is a candidate alloy defined by two composition/process parameters: an alloying-element fraction (0–30%) and a cold-work/anneal state (0 = fully annealed, 1 = heavily cold-worked) — the two knobs a real alloy-development program actually varies. Both output properties come from a smooth underlying structure–property relationship, not noise alone: strength follows a solid-solution/precipitation bump that peaks near a specific alloying fraction and rises further with cold work, while conductivity falls roughly exponentially with alloying content (impurity electron scattering) and drops a little further with cold work (dislocation/grain-boundary scattering). Realistic measurement scatter (a few percent) is layered on top of that curve, exactly like the trade-off real copper- and aluminium-alloy families (Cu–Ni–Sn, Cu–Cr–Zr, Al–Mg–Si) show between strength and electrical conductivity.
The gold points and connecting line are the Pareto-optimal frontier: a candidate is on it only if no other candidate in the pool beats it on both strength and conductivity at once. Every other point is "dominated" — there is always a better all-round choice already in the pool — and is drawn as a plain grey dot. This is the same multi-objective screening principle used in real high-throughput materials informatics (property-prediction models scan thousands of virtual compositions and keep only the non-dominated set for further experimental follow-up, instead of chasing a single "best" material that doesn't exist when two properties trade off against each other).
The filter sliders act as a screening step: raising the minimum strength or conductivity threshold dims out candidates that fail it and reports how many remain — mirroring how a real screening pipeline narrows tens of thousands of computed candidates down to a shortlist worth synthesizing.
