It provides interactive visualizations and business intelligence capabilities with an interface simple enough for end-users to create reports and dashboards. Power BI is a business analytics service by Microsoft. It can create a wide range of different visualization to present the data and showcase insights interactively. While Tableau is a powerful Business Intelligence tool that manages the data flow and turns data into actionable information. Power BI is a business analytics service provided by Microsoft that can analyze and visualize data, extract insights, and share it across various departments within your organization. Let's jump on to the significant differences between Power and Tableau and help you overcome some of the challenges. Often learners, practitioners, and researchers come into a dilemma to decide which one of the tools they should learn or use in their work. They help you perform data analysis, data manipulation, and data visualization to make sense of business data and draw insights. This tutorial is written by Gregor Aisch, visualization architect and interactive news developer, based on his workshop, Data visualisation, maps and timelines on a shoestring.Power BI and Tableau are two important Business Intelligence (BI) technologies for the collection, integration, analysis, and presentation of business information. The workshop is part of the School of Data Journalism 2013 at the International Journalism Festival.ĭownload and install Tableau Public. By now there is only a Windows version available.Ĭlick Open data to open the data import window. From the list on the left pick Text File and select eurostat-youth.csv. Note: if this step fails with an error message, try changing your system region to English in Windows control panel (see screenshot).Make sure that Field separator is set to "Comma". It seems that Tableau has cannot comma-separated values if comma is set as decimal separator for numbers in the system settings. Tableau now lists all the columns of the table in the data panel on the left. unemployed_15_24F: percentage of unemployed females between 15 and 24.unemployed_15_24M: percentage of unemployed males between 15 and 24.youth_unemployed: percentage of people that aged between 18 and 24, unemployed and do not participate in education or condary_edu: percentage of population with secondary education.The dataset contains the following columns (all data is 2011 and aggregated on NUTS-2 level): The columns are classified into Dimensions and Measures. Now we are going to analyze the dataset using Tableau. Now drag the field youth_unemployed from Measures to Columns. Then drag secondary_edu to Rows.Īs you see Tableau computes the sums of the columns instead of plotting the individual values. To fix this we need to right-click the green fields and select Dimension. If both fields are set to be treated as dimensions you should see a scatterplot like shown in the following screenshot. You can see that there is a negative correlation between education and youth unemployment. Now drag the field country from Dimensions to Color to color the plot symbols by country. You can also drag the country to Shape to change the icon.Īdd the fields country and geo_name to the Detail mark to include that piece of information in the tooltips. Now you can use the color legend and quick filters to highlight and hide certain countries. Now we can create a map easily: select the dimension lat and lon together with the measure count (while holding the Ctrl key) and click on Show Me to expand the list of suggested visualizations. Then click on the icon of the map with the blue circles. Now you should already see the complete table.Ĭlick on Show Me again to hide the panel. Tableau is smart enough to use the square roots of the counts for the circles radii automatically, so we don't have to care about this. You can make the circles transparent by clicking on Color in the panel Marks and moving the transparency slider. To change the size of the circles, click on Size and adjust the slider. Now drag the field name to the Mark Label to add the city names as labels to the map. Note: The final steps of this tutorial are going to be added in the coming days.Įnjoyed this?

Before the 1990s, economic educators were concerned with incorporating emerging technologies into instruction.
