The line graph illustrates the changing trends in participation for five different activities at a social centre in Melbourne, Australia from 2000 to 2020. The activities include film club, martial arts, amateur dramatics, table tennis, and musical performances.

In 2000, the film club had the highest number of participants, with around 65 individuals.This number remained relatively stable, fluctuating slightly and staying above 60 people throughout the observed period. Martial arts saw a moderate level of participation, starting at around 36 participants and experiencing minimal fluctuations over the period, ending with about 35 members by 2020.

Amateur dramatics began with about 25 participants in 2000, and this activity became even less attractive, gradually declining to only about 7 by 2020. Conversely, table tennis, which had fewer than 20 participants in 2000, exhibited a surge in participation, rising to around 55 by 2020, overtaking martial arts and amateur dramatics and finally securing the second position. Similarly, few people chose to participate in musical performances in 2000. However, this activity experienced a significant growth, particularly after 2005, and reached nearly 20 participants in the end.

In summary, it can be observed that the film club maintained the most popular choice throughout the two decades and table tennis witnessed the most dramatic increase in participation from 2010 to 2020, while amateur dramatics experienced a marked decline over the 20-year period.
