The line graph illustrates the proportion of visitors, in thousands, to three London museums (British Museum, Science Museum, Natural History Museum) from June to September 2013.
Overall, the number of visitors demonstrated significant changes across the three London museums. The proportion of the British Museum depicted a fluctuation. It remained between 500 thousand and 750 thousand from June to August, peaking at 650 thousand in September, the highest among the three museums.
In contrast, the pattern for the Natural History Museum expressed a downward trend. Visits dropped sharply between June and July, reaching below 400 thousand. It remained at the same level until August, before increasing slightly to nearly 500 thousand in September.
Science Museum visitors signified a significant decline. Visits slowly decreased from 400 thousand in June to 300 thousand in August, rising sharply approximately 450 thousand in September, slightly lower than the number of the Natural History Museum.
In summary, there were considerable changes in the number of London museum patrons over the four-month period, with the British Museum fluctuating dramatically, culminating in September, and the Natural History Museum decreasing consistently, except between August and September, while the Science Museum experienced a slow decline initially, then rising quickly in the final month.
