Data Chart Interpretation Tool — illustrative example

INPUT
Revenue chart rises from 100 to 120; axis starts at 95. Units and period are not supplied.

RESULT
Absolute change: +20 in the chart's units.
Relative change: (120 − 100) / 100 = 20%.
Presentation note: the axis begins at 95, making the visual rise more prominent than a zero-baseline view.
Missing context: currency/unit and time interval; no claim about growth speed is justified.

REVIEW
Interpret the chart's axes, units and time window before explaining the pattern. Visual slope can be distorted by scale choices.

This is a teaching example, not a live execution record.
