Dashboard Week #4
Today we had a special task! We had to create a viz using other software different than Tableau. My choice was Power BI, after giving a try to Flourish (and giving up after an hour). We were given Skiddle API to extract events data. I chose to extract events within 50 miles from my house

Distance between two points using Alteryx
Using fundamental Spatial analysis in Alteryx is pretty easy, thanks to some of the tools, which do all the work for us 😊. This time we are going to calculate the distance between two points on the Earth, a basic measure in the Spatial world, which might come handy sometimes
