A Line Chart with Markers is an enhanced version of the traditional line chart, where key data points are emphasized using dots, circles, or symbols. This style became popular in financial journalism and technical analysis tools in the late 20th century, as digital charting systems allowed for interactive visualization. It was widely adopted by Bloomberg Terminal, Reuters, and stock market software to highlight key price movements.
