The beauty of using Tableau in the eyes of a first time user

Last week, I have been introduced to a new visualization tool that is yet again, new to me. The tool is called Tableau.

Tableau is a data analysis application used in the business intelligence industry that is both effective and rapidly growing. It aids in the simplification of raw data into a format that is simple to comprehend. Tableau assists in the creation of data that is understandable for experts at all levels of an enterprise.


Sweet and simple. Two words describe perfectly my impression of using Tableau for the first time. Our professor gave us an introduction and a demo. I was quite impressed with the user interface. It really has this user-friendly look and it gives a professional vibe.

Am I dreaming? This is the first time that came into mind when our professor started the demo. This tool is so amazing, it only takes you to upload the dataset of your choice, drag, and drop labels to the bins, and voila! It’ll automatically give you suggestions and various types of visualization for you to represent your data.

The great thing about Tableau software is that it doesn’t require any technical or any kind of programming skills to operate. I am grateful for this right now since I am new in the data science world and I am still learning to program. The tool has garnered interest among people from all sectors such as business, researchers, different industries, etc.

Tableau links and extracts data from a variety of sources. It can get data from any site you can think of. Tableau can collect data from a basic database like Excel or a complex database like Oracle, as well as databases in the cloud-like Amazon Web Services, Microsoft Azure SQL database, Google Cloud SQL, and a variety of other data sources.


We were given a task to publish the visualizations that we were able to make using the given dataset. There was an internet connection outage in our area on the day of submission. I was also hoping to improve my work before publishing it. The internet connection came back just a few hours before the deadline. I was in panic mode since I feel like I can somehow improve my work. For my initial work, I have bar charts. I tried playing with dragging different labels, putting them in bins, and also played with different functions. From the simple bar charts, I was able to make an interactive Geomap, Treemaps, and my personal favorite, the bubble charts.

My work published few mins before the deadline

Luckily, I was able to finish and publish my work just a few minutes before the deadline of submission. I’m so grateful that tableau is a very user-friendly tool. I am really looking forward to using this for my future work and project. I know there is a lot of room for improvements for my work and I am excited to dig deep and learn how to utilize this tool more effectively!!/
