An analyst observes an income distribution chart showing various countries. For Country X, a high-income nation, the bar representing the richest 10% is visually much taller than the bar for the poorest 10%. For Country Y, a low-income nation, the bars for the richest and poorest 10% are both very short, with a barely perceptible difference in height. Explain why it would be a mistake for the analyst to conclude, based only on this visual information, that Country Y has less income inequality than Country X.
