In Professional life, I am working as a Senior Consultant with Beinex, India. I always had a passion about Data Visualization, where one was able to explain a concept by means of visuals which makes it easier for the audience to understand about that particular concept. (It doesn’t matter whether they have already aware of the concept or not)
I started my career in an IT organisation, where I got a chance to learn Tableau. Then, I realized the power of Tableau in Data Visualisation. I tried to explore more about the Tableau by creating different types of charts (sankey, waffle, network charts), etc.
I frequently participate in #MakeoverMonday Project by Andy Kriebel (@VizWizBI) and Eva Murray (@TriMyData) which helps me to shape up my data analysis and data vizualisation skills. (I was lucky enough to get a swag (water bottle) from #MoM for 1000th submission, which gave me a lifetime memento) https://twitter.com/VizWizBI/status/1090659140765208576
I just always wanted to explore my design and artistic skills with data visualization and it worked out most of the time. Also, I get constant support and appreciation from the Tableau Community which really cheered me to do more and more. I want to take this chance to thank #Datafam who supports me all the time.
Michael: Hello Pradeep. You recently posted your IronViz 2019 submission on Tableau Public. It is titled U.S. Farms and Farmers Under Threat.
Can you tell my readers the process you went through to develop this data visualization? For example, how you gathered and prepped the data, created the design, and translated that into Tableau?
Pradeep: I still remember the time when I was doing my first Iron Viz 2018 (Water Feeder). That time I was absolutely new to Tableau and I just thought of giving it a try. I just downloaded the data from public government site and created visualization about Monsoon patterns in India
Luckily, I made it to the Top 10 (7th position) and also, I got feedback (from judges) mail which helped me to correct my mistakes regarding design, analysis and storytelling.
Since then, I was badly waiting for #IronViz 2019 to participate. I was happy to see the topic is about ‘Agriculture’, but I was a little bit worried to know that we have to use only the provided dataset by the U.S. Department of Agriculture. I have just gone through the dataset, it was huge and confusing at the same time. I have decided that, however complex the data may be, I don’t wanna give up for that reason.
Instead, it gave me a motivation to participate. Then I just took a while to understand the given data. I thought of concentrating on 5 major challenges from the given dataset. Then I selected those particular measures and ignored the other ones. (I used Excel for data preparation)
I wanted to create a simple but effective design. My only aim was to highlight those 5 challenges in a simple way that anyone who sees the viz could understand it at ease. I added some key points and visuals (waffle, donut charts) beside each challenge which would make the audience to relate them with the problems. I have used 5 color codes (magenta, blue, green, orange and purple); each color for each problem that would help audience to have a clear and separated view on each problem. At the bottom, I have added “What can we do?” part giving my suggestions to overcome from the mentioned challenges.
I always remember the feedback (Iron Viz 2018) in my mind, and I have implemented them in this year’s #IronViz submission. Also, I wanna thank the Flerlage brothers (Kevin Flerlage @FlerlageKev and Ken Flerlage @flerlagekr) who have helped me a lot by giving me constant feedback and support which shaped my viz into a wonderful one.
Michael: You are a Senior Consultant at Beinex. Can you talk a little about how you can help businesses in their data visualization needs using Tableau?
Pradeep: I have recently joined Beinex as a Senior Consultant and I feel really great working with Beinex team to help people understand data.
We emphasize on self-service analytics. We take business users on an adoption journey to ensure they know how easy it is to conduct analytics using Tableau. We focus on understanding the requirements of the business, creating multiple prototypes and suggesting industry best practices with respect to KPI measurement and visualization techniques.

At Beinex, I have got opportunity to work with client C-suite level directly and see how data visualization solutions helping them to solve many business problems.
Michael: Can you tell us three of your favorite Tableau Desktop tips and tricks?
- “No Polygons” by Kevin Flerlage (@FlerlageKev) was one of my favorite tricks.
Inspired by his work, I have tried creating my version of “Four Leaf Clover Chart” following the same technique.
2. “Color Theming in Tableau” by Ken Flerlage (@flerlagekr)
Inspired by his work, I have come up achieving the same trick using single sheet and parameter in my viz “Elevated Measles Risk”, a #ProjectHealthViz (Topic- Measles) by Lindsay Betzendahl (@ZenDollData)
I have also done a guest blog post about this trick in Rajeev Pandey’s (@rajvivan) site https://vizartpandey.com/dynamic-background-color-in-tableau-using-parameter/
3. “How to Create Actionable Sparklines” by Andy Kriebel (@VizWizBI).
I personally believe spark lines are simple and powerful way of data representation.
Michael: Back in December of last year, you published a data visualization titled How Americans plan to quit smoking in 2019? I think the use of burning cigarettes (including the ash) as your horizontal bars is very creative. Can you tell my readers how you created the cigarette horizontal bars?
Pradeep: Yes, I still remember the time when I have created the viz related to smoking issue. Last December 2018, I have read an article in Insider.com about “How Americans plan to quit smoking in 2019?”. This topic really attracted me and I just wanted to convey this topic in an interesting way using Tableau. So, I decided to use cigarettes as bars.
It was really fun creating this viz and it was simple to create, as well. As most of the tableau people knows that we can add an image/shape at the end of the bar using dual axis. I used the same trick. I made white horizontal bar chart and added cigarette ash (shape) at the end of each bar. I created the ‘cigar end’ (shape) for bars in a separate sheet and then I just placed both the sheets side by side inside a container 😊
So, a cigarette bar has three parts (Cigar end, horizontal white bar and ash shape)
I also used transparent sheet trick, background image, added info about “Reasons to Quit Smoking” which would add more flavor to the overall viz.
Michael: If you could magically be alone in a room with Francois Ajenstat, what would you ask him to add into Tableau Desktop?
Pradeep: Tableau is one of the most fast-growing data visualization tools in the market. It is the best way to change or transform the raw set of data into an easily understandable format by powerful visualizations.
I love using Tableau all day because of its flexibility and stunning visuals.
If I had a chance to meet Francois Ajenstat, I would ask him to add few things in Tableau Desktop which are as follows:
- Adding charts like Sankey, Radar, Gauge/Speedometer, Waffle chart types in “Show me” tab by default.
- Adding an option to rotate (Slightly to left or right) the sheets in dashboard.
- Adding an option to remove all the grid lines/ axes rulers at once, that will save a lot of time.
- Tooltip enhancements like changing tooltip background color.
Michael: What is next on your “To Do” list? What can the Tableau community expect to see from you in the near future?
Pradeep: I have 4 things in my ‘to do’ list:
- I’m eagerly waiting for the #IronViz 2019 feeder 1 results and I wish my viz to be featured at least in top 10.
- Participate regularly in #MakeOverMonday, #ProjectHealthViz and #WorkoutWednesday to develop my data analysis and visualization skills.
- I wish my viz to get featured in Viz of the day #VOTD by Tableau Public.
- To complete ‘Tableau Desktop
Specialist’ certification by the end of this year.
