The line graph depicts the proportion of households with internet access in four countries over a twenty-year period, measured in percentages.

Overall, it is evident that internet usage increased substantially in all countries, although the rate of growth differed. Notably, Country A maintained the highest proportion throughout, while Country C experienced the most dramatic rise.

At the start of the period, Country A accounted for approximately 40%, subsequently rising steadily to around 70% by 2010, before continuing a moderate increase to just above 70% by 2020. Country B followed a similar upward trajectory, beginning at roughly 35% and climbing consistently to nearly 65% over the same period.

In contrast, Country C started at a low 15%, but witnessed rapid growth, surpassing 50% by 2015 and reaching almost 60% in 2020. Country D displayed a gradual but consistent increase, rising from 25% to approximately 60% by the end of the period, closing the gap with the leading nations.
