Pro tip for #positconf: lanyards naturally hang your nametag rather far from your face, which can lead to an awkward downwards scan for someone who is looking at your face to read your name. You can either a) shorten the lanyard by tying a knot in it or b) bringing a different nametag holder!
Picture of me illustrating where name tags tend to sit when hung from a lanyard, which is basically around my belly button, as compared to the normal spot of being in the upper chest area

Sometimes, data visualization is about using charts to illustrate a key point or conclusion gleaned from analyzing the data. But what if you’re not sure what the conclusion is? Presenting examples from news reporting on the topics of elections, polling and economics, I will talk about how I have grappled with uncertainty and how to communicate it to the public.
