Nai Louza

After working with SPSS for several research projects, Nai discovered a way to bring analysis to life using Tableau’s simple and effective framework for data visualisation.  Although she has not discarded spreadsheets, she uses Tableau to fully explore data and light up new points of insight.

When she isn’t geeking out over data, she spends her time at spoken word poetry events throughout London, brushing up on her Arabic, and tending her forever-failing herb garden.

Tableau 9.3 and Easier Mapbox Customization

I’ve done a lot of different courses in my life and more often than not, I leave feeling like a part of me has shifted and that I’ve soaked up knowledge that nourishes my headspace and allows new ideas to grow. My time as a data schooler has been no different, and I...

Putting the “Table” in Tableau

Tables are something that people often ask of data analysts, mostly because its something they’ve gotten used to over the years using Excel spreadsheets. Tables have their time and place, but there are often better ways of presenting data to gain valuable insight...

Highway of Tears: Mapping Our Stolen Sisters

  Although I finished this visualisation a while ago, I’ve been gritting my teeth to write a blog post about because honestly, it just doesn’t feel right. This blog was going to outline the process I went through to create this visualisation and some of the...

Editing Tableau Public Workbooks

Although this might seem like simple to some, last week when I wanted to update a workbook I had uploaded to Tableau Public, I just could not figure out how. I started out by opening the original packaged workbook on Tableau Desktop, making my edits, and then saving...

#TipWeek: Getting PDFs from Tableau Server

For my final #TipWeek tip, I’ll be focusing on a Tableau Server command that may prove helpful at some point. If ever you find yourself working on Tableau Server and want to download one of your views as a pdf, it’s as simple as a tabcmd command. First, navigate to...

#TipWeek: Beyond the Presets – Custom Mapbox Maps

A couple weeks ago, Anuka published a post that shows you how to use the new Mapbox integration in Tableau (link). Her post outlines how to bring in Mapbox’s preset maps, which are absolutely stunning on their own: However, if you want to edit these maps and bring in...

#TipWeek: Creating a Bulk Download Input List in Alteryx

Yesterday, I walked you through the process I used to do a bulk download of zip files from the U.S. Bureau of Transportation Statistics (see here). Although that process only used two tools in Alteryx, input and download, the process to create the input file in...

#TipWeek: Bulk Downloads with Alteryx

This dashboard is based on data from the U.S. Bureau of Transportation Statistics that contains all flight data for U.S. airlines from 1987 to 2015 (link). ALL. Flight. Data. I’ll give you a moment to wrap your brain around that. Suffice to say, it’s a lot of data....

(Don’t) Show Me: PART 3 – Gantt Charts

We’re on the last stretch of (Don’t) Show Me and for this final demonstration, I will demonstrate how to construct Gantt charts. Gantt charts are used to show duration across a variety of dimensions. For example, let’s say you want to create a view showing the average...

(Don’t) Show Me: PART 2 – Histograms

This week I’ve been demonstrating how to create certain graphs without Tableau’s “Show Me” feature. Why? Well first, it’s always good to dig down and figure out exactly how Tableau creates the views that it does, based on what data and calculations. Second, creating...

(Don’t) Show Me: PART 1 – Box-and-Whisker Plots

One of the great things about Tableau is that it’s been designed for anyone to be able to install and run insightful analyses within a matter of minutes. A drum teacher of mine used to say, “make the easy s*** look hard, and the hard s*** look easy,” and a lot of the...

Fixing Fixed Average Lines

When working with average lines, sometimes you want to click on a point in your data and still be able to compare to the original overall reference line. Tableau makes it easy to keep your reference line fixed by simply unchecking the “show recalculated line” option...

Correlations, Trend Lines, and Formulas in Tableau

Last week, I spent some time working with the 2015 English Indices of Deprivation, and felt a bit of nostalgia for my days as a research assistant working out trend lines and Pearson correlations. So I decided to do a throwback to those days with this viz, and boy was...

ParseHub – the next Best Thing for Data Analysts?

UPDATE: Craig Bloodworth has created a data web connector that will import data from ParseHub directly into Tableau. You still have to wait until ParseHub has extracted the data on its servers, but you do not need to download the CSV file if you connect directly with...

Apples and Oranges

Tableau is a pretty straightforward program and it’s been built on the idea that anybody can learn to create some pretty awesome data visualizations with limited experience. However, there are some elements of Tableau that need a bit deeper of an understanding if...
