Create a 7-second line chart on a near-black background. The title "Weekly active users" sits top left and a large white number top right. An orange line draws from left to right across seven months (Jan to Jul) over a fading orange gradient fill, while a white dot with an orange halo rides the tip and the big number counts along with it from 1,200 to 5,200. At April, a white ring appears on the line with a thin stem and a white label "Video launch". At the end the big number turns orange.
