 The `dash_vtk.PolyData` element has an additional property to automatically generate cells based on some assumption of the order of the points defined in the `points` array. That property is named __connectivity__ which default to `manual` meaning no automatic action is taken. But that property can be set to `points` to automatically set the vertex to actually see the points provided or `triangles` which assume to use 3 concecutive points to create a triangle and finally `strips` which then assume it is a single triangle strip consuming all the points.
