A sparkline is a small, condensed line chart designed to be embedded inline with text or in dashboard cells. It shows trends at a glance without axes, axis labels, or detailed scales - pure data visualization in minimal space. The defining characteristic is extreme minimalism: a single continuous line that conveys the shape of data without any chart chrome.
