7 Tips For More Effective Visualizations

1 Start with the story you want to tell. Whatever your specific goals may be, when you create a visualization, you’re really trying to capture a snapshot of your business – a quick, visual story that will drive understanding, discussion, and decision-making. To do this, you need to understand the data you’re working with and determine what story you want to tell. Start by asking a few questions. UNDERSTAND YOUR DATA • How many data sets are you working with and can they be combined? • Is your data qualitative or quantitative? • Is there external data you want to include? • How accurate or fresh is your data? DETERMINE YOUR STORY • What are the key messages you want to convey? • What do you want your audience to think, do, or feel? • What details will lend credence and support to your story? WHAT STORY DO YOU WANT TO TELL? Good visualizations highlight relationships between data which can tell a powerful story. Outliers illuminate deviations from the norm. Trends indicate changes over time. Patterns show repeated, consistent characteristics. Correlations communicate relationships between two or more variables. 2 Variable width chart Visualizations Bar chart Bar chart Circular area chart Line chart According toTableQlik Visualization Advocate Dr. Patrik Lundblad, there are four fundamental Line chart Variable width chart or tables with Bar chart horizontal charts Visualizations types of dataembedded visualizations, each of which can provide specific insights: Bar chart Table or tables with embedded charts Bar chart horizontal COMPARISON VISUALIZATIONS Table Table or or tables tables with with embedded embedded charts charts ANSWERS Which products sell best?
