🎉 Excited to share that my report for the Microsoft PBI10 contest made it to the Advanced Favourite List. This experience reminded me that growth often happens outside our comfort zones, in the moments we dare to try. @RxDono thanks for riding with me, you’re amazing 🙌

The One Time the Scatter Chart is not so confusing. I'll admit it, the scatter chart is usually that one visual stakeholders ask to skip. Too messy. Too abstract. Too analytical. But this Gartner-style quadrant flipped that script @ZoomCharts #Builtwithzoomchart
