    Ik zie dit soort animaties de laatste tijd vaak langskomen, met tal van onderwerpen (sport, muziek, politiek). Het is echt een dramatisch slechte datavisualisatie. Van 2002-2020 wordt de horizontale as een factor 2 ingezoomd. De belangrijkste boodschap wordt zo weggemoffeld.

    In December, signed a letter lobbying US administration against publishing. This resulted in petition & public pressure. APS now published clarification & new letter, stating they "regret signing this letter". Glad to see the board remedied this mistake.
