Which graph has a line connecting data points?

• A. Line graph
• B. Bar graph
• C. Pictograph
• D. Pie chart

Answer: (A)

A line graph is designed to show how values change over time or across a sequence by connecting data points with a line. That continuous line makes trends—whether values rise, fall, or stay steady—easy to see at a glance. Bar graphs, pictographs, and pie charts present data in different ways: bars show comparisons between categories, pictographs use icons to represent amounts, and pies display portions of a whole. None of these link data points with a connecting line, so they don’t emphasize the progression or trend as a line graph does.
