“3 years ago, I hit “post” on my first-ever #datadna data visualization challenge entry on LinkedIn (by Onyx Data). It was around this time of year (a Christmas song analysis), and I remember the nerves I felt when I shared that Power BI dashboard.
Fun fact: one of those first dashboards – a Power BI resume – did not only win, it is still the most downloaded report on my website.
I am really happy that I am now, 3 years later, a guest judge for the December challenge. For anyone second-guessing whether they really should participate and wondering, “What if my network doesn’t like it?” Just do it! You never know where it might take you!”
