![]() After creating this Tableau workbook, dashboard, etc., I could then share it with others who have access to this database, and the visualization would just need to be updated with new data at regular intervals or on an ad hoc basis. I would know in advance what columns I'm working with and their meaning. I could use Tableau Desktop to create some standard visualizations and connect it to the database. The task of creating visualizations would be fairly simple if my data was stored in a database. ![]() But Tableau Reader won't give you much beyond that. In addition, any user with Tableau Reader, a free Tableau product, can open a TWBX file and view your worksheets (individual plots) and even apply filters if you've supplied them. You don't have to worry that the user will not have permission to access the data, since the data is embedded with the visualization. The TWBX format also makes it easy to share with others or publish to a Tableau server. For example, a 30 MB CSV file and 100 KB TWB file inside a TWBX archive file resulted in an overall size of less than 1 MB. Using the TWBX archive file format greatly reduces the size of the data set, since it gets compressed. Once you've generated the XML that makes up the TWB file, you can either use this TWB file directly with your data set or package your data set with the TWB file into a Tableau TWBX archive file format. Since Tableau uses XML behind the scenes to represent a workbook-its data, worksheets and configurations-you can generate a Tableau workbook (TWB file) using a general purpose programming language. It turns out, although Tableau documentation to enable this effort is limited, it is very possible, and I'll explain how to do it. I wondered if I could use Tableau to create plots or visualizations from these data sets programmatically. ![]() Since Tableau is the market leader in visualization, analytics and business intelligence capabilities, I decided to explore Tableau. I recently had a need to produce visualizations (plots) of scientific data from data sets (CSV files) produced by running a statistical application.
