Show tooltip in bullet visualizations

Description - Show a tooltip in Bullet visualisations to report the value of that bullet.

Why is this feature important to you - It is impossible to see the value that a bullet reports. Comparing it to the axis is impractical when reporting small values or values of high precision. Also, other visualisations have such tooltips, so why not bullets too?

How would you like the feature to work - When mouseover a bullet (green portion), show a tooltip reporting the value. Similar to the tooltip shown in bar charts.

Current Behaviour - Nothing happens when you mouseover a bullet.
