Using Tableau Desktop, you can create Visualizations from information stored in your spreadsheets and databases, giving you the ability to quickly perform data analysis with dynamic and great looking Dashboards.
Using Maps in Tableau allows you to perform geographic analysis by plotting data points on a Map. You can accentuate geographic elements to enable easier data analysis. Maps are good for illustrating geographic trends, comparisons and relationships, and allowing users to drill down for more information.
There are five types of maps you can build in Tableau:
- Proportional Symbol Maps – showing quantitative information for locations
- Choropleth Maps – filled maps useful in showing ratios for comparison
- Point Distribution Maps – plotting points on a map to highlight data points visually
- Flow Maps – tracking the path of something over time across a map
- Spider Maps – tracking where origin location and destination locations interact
