Can I have specific points on a line graph have a label?

[willspub]

I want to display a label showing the highest and lowest points on a line graph.

Is this possible with Nivo?

For example:

[
{x: 1, y: 99999}, <--- this can show some kind of label on the graph.
{x: 2, y: 100},
{x: 3, y: 1},   <--- this can show some kind of label on the graph.
{x: 4, y: 400}
]
