ECLSS Development Schedule Risk Simulator — 2D Gantt & Histogram

This 2D companion to the 3D ECLSS schedule-risk simulator drives the identical Critical Path Method and Monte Carlo schedule-risk model — the same 11-task dependency network, the same PERT single-point estimate, the same triangular-distribution sampling of task durations — but renders it as a flat, pannable and zoomable Gantt-style critical-path diagram stacked above a live bar-chart histogram of possible project-completion dates. Adjust the duration-uncertainty multiplier, trial count and target deadline, or drag the amber deadline marker directly in the histogram, to see how schedule risk — not just the nominal plan — should drive real spacecraft hardware-integration project decisions.
