Spark Line

A Sparkline is a small chart that is drawn without axes. It does not contain some chart-specific elements (such as legend, title, etc.). The Sparkline chart can be easily embedded in the text as it performs more like an inline element (rendered inside a span) as opposed to the standard charts, which behave like block elements. The primary purpose attached to the Sparkline Chart is to show a trend of something unique.
