Which element is considered less effective in a dashboard designed for narrower displays?

A multi-value component is considered less effective on narrower displays because it often requires more horizontal space to clearly present multiple data points simultaneously. On narrower displays, the screen real estate is limited, making it difficult to convey the information effectively without causing clutter or making it hard for users to interpret the data at a glance.

In contrast, single value components can efficiently deliver key metrics, line graphs can show trends over time in a compact manner, and bar charts can compare values with clarity. These formats can adapt more easily to limited screen widths, allowing users to draw insights without overwhelming them with too much information at once.
