Description

Similar to

the visualization tab of shinystan should have an option to show how the Markov Chain moves, perhaps using different colors for the different chains, in two or three dimensions (with one dimension usually being lp__). I am thinking that one point would show up at a time (perhaps with a half second pause) big and bold at first and then have its point shrunk along with more transparency once the next point comes up.

Research direction

Start in the shinystan visualization tab and read the linked Stan Users discussion for the intended Markov-chain evolution view. Define how chains, dimensions, point timing, shrinking, and transparency should behave; done means the visualization can show chain movement in two or three dimensions, typically including lp__, with distinct chains and sequential point animation.
