Best Viz advice when starting with Tableau – find data on something you love and create something from it. It is always easier to feel invested when you are exploring the data of a topic that fascinates you. Check Tableau public for data sources and ideas on your favorite subjects. Try and look at it from many different angles and using different visualization techniques (a good reference guide for vizzes by type like Data Visualization by Andy Kirk).The real key to getting good visualizations easy is to get the data in the right form.

Best advice when starting with Alteryx  –  learn the tools, throw each one on the canvas and practice using it. An analyst is only as good as their tools, so start with the sample workflows in the Help and then look at the Weekly Challenges on the community.

Best Viz advice when starting with Tableau – In real estate, it’s all about location, location, location but if you just started learning Tableau is all about reshape, reshape, reshape, your data. If you can master the aspects of getting your data into the right format then there is no limit to what you can accomplish with Tableau. After that it’s all about simplify, simplify, simplify your viz!
