In this course, we're going to show you how to build Tableau dashboards that turn raw data into compelling visual insights that can empower you and your viewers. We will show you how to build a range of visualizations, such as bar charts, box plots, heat maps, and much more.

The course will also show users how to format charts correctly, add labels to axis, perform conditional formatting, and even include interactive tool tips. But before we fire up Tableau, let's ask ourselves some fundamental questions. And the first is, what is a dashboard? And well a dashboard is simply an easy to read, single screen interface that shows the key performance indicators for a business unit. And dashboards are used in a number of business contexts.

Firstly, a dashboard provides a manager with a quick, high-level overview of the business on either a weekly, monthly, or even quarterly basis. Next, dashboards make it easier to spot trends and obtain insights from raw data. And they also ultimately lead to better decision making and better results. You may have seen in other courses dashboards built in Excel. So why do we want to use Tableau? Well Tableau is an extremely powerful visualization tool and has much more interactive features than Excel. What's more? Tableau has very fast deployment time, and you'll normally build dashboards in minutes rather than hours in Excel. Next, Tableau can connect to and join multiple data sets to your dashboards. And these data sets can be much larger than simple Excel files, particularly if you're connected into a server, which may have hundreds of thousands or even millions of rows.

For this course, we're going to use a case study of an accountancy firm that has 21 accountants and would like to use Tableau to gain some insights into the customer base, employee performance, and divisional performance. Our task is to build a couple of dashboards drawing from three different data sets to help the managing partner gain some valuable insights into his business.
