Products that do what lpviz – Interactive linear programming visualization in the browser does

https://github.com/lpviz/lpviz Visualize 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.

    Hi HN! I’m Alex from Parabola (https://parabola.io). Parabola is a visual programming tool for creating functional data flows that everyone can use. It’s entirely drag-and-drop, handles data sizes much larger than a traditional spreadsheet, calculates everything live, and can run your flows on a schedule of your choosing. I used to work in strategy consulting, doing data analytics for SMBs and Fortune 500 companies. The amount of time wasted on menial tasks was astounding. Things like cleaning data, generating custom reports, creating human workflows to solve shortcomings in third…

    Hey HN, I built a tiny zero DOM layout engine for vector graphics and custom renderers to resolves nested rows/cols/grids into exact `{x, y, w, h}` boxes, with text measurement, overflow signals, and collision separation. This is to help make SVG, PDF, Canvas responsive. Feedback welcome from anyone building canvas/SVG diagrams, dashboards, node editors, or diagram tools.

    http://ghn.cloudapp.net/ If you can, try right-clicking on an image. This page started off as a random collection of stuff I wanted to try out (spinning up an Azure linux VM included) where I gave myself "1 hour per feature" to learn new stuff. Shell scripts, command-line webkit-based png rendering, pcntl_fork, piwik... Fun stuff. I know, yet another view of HN, no biggie. I welcome all feedback and questions!

    This was submitted before but it didn't seem to get much attention because I don't think the title was very descriptive and the submitter was brand new. I almost didn't click it but once I did I thought the project was pretty awesome and had a lot of promise. Hope this doesn't violate the rules, I have no horse in the game, but the creator is here on the site so hopefully he'll be able to answer your questions.
