Currently when a Watchlist is created, a card is produced on the Home Page as expected.

For certain visualisations, this works well and automatically resizes the visuslisation to fit in the Watchlist view (e.g, treemap or donut chart) but for other visualisations (typically larger charts e.g., pivot table / donut chart with column trellis) this creates a scroll bar, and you can only see limited information on screen.

It would be an excellent feature to be able to drag/resize each card, to allow the end-user to see all information included in the visulisation.
