The given line graph demonstrates data on the quantity of people for various types of activities at one social center in Melbourne within 20-year period from 2000 to 2020. In general, film club remained the most popular within the period given, whereas amateur dramatics showed the reverse trend, being the least participated by 2020. Three other activities illustrated different trajectories, including table tennis as the most increasing; marital arts showing constant stability; and musical performances giving the lowest result in the beginning.
Where film club and martial arts are concerned, they went through the steady trend, with almost 65 participants in the beginning, to a little growth in approximately 68 people in 2020 for the former, and with no improvement from 35 despite the fluctuations in 2010, with just a bit below 40 for the latter.
On the other hand, table tennis and musical performances showed the consistent development. Table tennis started at just 25 people in 2000 and then increased barely in 2005, went down in 2010 with the figure of 20 participants, and then reached its peak in 2020 at about 55. Musical performance also experienced the upward trajectory, beginning at only 0 in 2005 and then peaking at just under 20. In contrast, amateur dramatics lost its popularity in comparison with 25 in 2000 and under 10 participants in 2020.
