The given line graph illustrates the changes in the number of participants engaged in various activities at a social center in Melbourne, Australia in a 20-year period starting from 2000.
Overall, the number of participants in the Film Club consistently dominated the others throughout the period. Another noticeable point is that except for the Musical performances and Martial arts groups, all other recreations witnessed a gradual growth.
In terms of the Film Club, in 2000, the number of participants dominated with around 62 individuals. The figure slightly dipped to 60 in 2015, but then grew steadily to 65 in the final year.
Regarding the other programs, the Martial Arts experienced a fluctuation of around 36 participants, with a peak of 39 people in 2015. Table Tennis participation began at a modest point of 15 members in 2000, and then marginally rose to 20 by 2010 before dramatically soaring to over 50 in 2020.
Similarly, the Musical Performace group had no participants in the first 5 years, but then quickly increased to 14 in 2010 and continuously grew to 18 in the last year of the period. In contrast, the number of Amateur Dramatics only grew by 2 in 2005, then demonstrated a significant fall in the next 15 years before hitting the bottom of only 5 members in 2020.
