What is your Christmas tree’s call to action?
Is it the star on top of the tree, the most visible and eye-catching, or the space in front of the tree, prepared to receive the gifts?
Sometimes you work so hard to show all the data in a way that enables readers to understand all the aspects of it, that you may forget you also need to call for a specific action.
If you take the example of the sparkline charts, this call can be done by highlighting a point or a part of the line, usually towards the end, using a unique colour (e.g. red).
For before/after comparison charts the call can be represented by a histogram bar coloured in red to show the reader where they need to focus next.
For timelines, the call can be embedded as a visual element representing a predicted trend for the next year, a new version arriving soon, or a parallel event requiring adjustments for your customers.
For me, the Christmas tree is a giant call to action in itself, as it calls for us to be generous and happy as children can be.
