How are sparklines and data bars different from other chart objects in Excel? What are they commonly used for?

What will be an ideal response?

Sparklines are small charts that are embedded into individual cells within a worksheet instead of floating above the worksheet. They are useful for analyzing trends in data. Data bars are components of conditional formatting. Like sparklines, they are embedded into individual cells within a worksheet and use bar charting to display the differences in the numeric data to which they are applied.
