The given line graph depicts the number of weekly patient visits across four distinct hospital departments between 2000 and 2012.
Overall, all departments exhibited a general increase in their number of weekly patients despite varied growth rates. Notably, the dental department consistently attracted the largest number of patients, whereas the infertility department displayed the most volatility.
In detail, the dental department commenced with 200 weekly patients in 2000, and this figure progressively increased to reach 300 patients in 2004 before peaking at 400 patients by 2012, representing a notable growth in popularity. The vision department also displayed a significant upward trajectory, starting with 120 patients in 2000 and escalating to 300 patients by the end of the period.
In contrast, infertility showed a more fluctuating trend, starting at 150 weekly patients in 2000, peaking at 250 patients by 2008, and ultimately falling back to 200 patients in 2012. Diabetes commenced modestly at around 100 patients per week, before seeing a moderate increase to 150 patients and staying at this rate until 2008. During the final four years, the number of diabete patients considerably rose to 250 patients, enabling it to overtake infertility and become the third most popular department.
