I write about adolescence and youth a considerable amount and the eco-anxiety alone with teens feeling helpless and hopeless from adult missteps on policy and practices worldwide so it's worth investigating further
Though WHO had great info on ages 10-19 w/fact sheets: https://www.who.int/news-room/fact-sheets/detail/adolescent-mental-health I chose to focus on the larger "World Data" charts to deconstruct the data viz by topic to see how "at a glance" we could discern patterns...Bar graphs quickly depicted anxiety as being most prevalent but it would've been nice to have an age breakout generationally to improve and note patterns.
I liked the scatterplot use of color, size of dot and regional side menus to enhance and refine mental health disorders by gender and country: https://ourworldindata.org/mental-health
Interactives that allow people to engage/mouse over areas of interest always impart deeper dives with personal data I think, though they did a good job using basic color mapping globally to assign percentages of depression for example, too. In short, I think "Our World In Data.org" encompassed every map, plot, chart mechanism we studied in one fell swoop, so it was fun to take one over-arching topic and see it layered into different ways of imparting the info. Now can we do one specific to youth age 10-19? ;)
