Data visualisation tools - which tool is best? Wrong question. The real question: what are you actually trying to achieve?

I built a dashboard. Scoped it properly. Delivered exactly what was asked for. Then heard the soul-destroying words: "This isn't something I'd feel comfortable showing my clients."

What I learned: the fanciest dashboard means nothing if it doesn't solve the problem. And when the shit hits the fan in a demo? Stay humble, ask questions, don't be a deer in headlights.

Tools matter less than you think. Understanding what people actually need matters more than you realise.
