https://github.com/lpviz/lpvizVisualize linear programming solvers - Simplex, Interior Point, PDHG, and Central Path - in the browser. Drag the objective/vertices/constraints around and watch the solver trajectory respond in real time. Enter 3D mode to view solver metadata (like centrality for IPM or KKT residual for PDHG) on the z-axis. Always happy to get feedback and feature requests, one thing that is coming soon is support for importing problems from e.g. JuMP or cvxpy.
