3D plots not displaying

On a fresh Anaconda 3 install over Windows 10, the vism view command runs, but it only displays about half of the plots that it should:

I suspect that this is partly due to my installation, but the path I took was naive enough (installed freshest version of Anaconda, chose Python 3.6, then did pip install viscm) that it probably also hints at problems that might be more broadly shared.

On a similarly-worrying note, the viscm edit functionality seems to be dead on my machine - it just reverts right back to the prompt:

I suspect you need more diagnostics / version nos. / etc.; please let me know which ones you need and how to obtain them.

まず、Windows 10 上の Python 3.6 を使用する新規の Anaconda 3 インストールで vism view と vism edit を再現します。表示されるプロットとプロンプトの動作を期待される結果と比較し、その後、原因を絞り込むために要求されたバージョン情報と診断の詳細を収集します。
