Chitra- Best advice would be to learn and practice, spend as much time you can on Tableau working with data, to create impactful stories you'd need to understand your data, learn ways to manipulate it, grab some good books on Data Visualization (these teach you visualization best practices), be creative with data, find inspiration from other vizzes and add your own flare to it. There is no single approach to get to that level, every person is different, all it takes is curiosity and passion.
It's all about pratice. My suggestions are as follows:
1) Take a training course. This definitely helps you to get your footing. But, it doesn't have to be an in-person course. There are some fantastic online courses that are available at a relatively low cost. I personally recommend this one from Matt Francis. It's what I took when I got started: Tableau 10 for Data Scientists
2) Practice. Find opportunities to practice. Fortunately, there are lots of ways to do this. Check out the following community projects as a starting point: Makeover Monday | A weekly social data project, Workout Wednesday – #WorkoutWednesday, https://www.vizforsocialgood.com/. Or you can find interesting data and just try to visualize it.
3) Leverage Tableau Public. Tableau Public is a freely available verison of Tableau. It has a few limitations in its connectors and requires that you upload your workbooks to their public server, but otherwise, it's an amazing tool to learn Tableau and it's absolutely free.
4) Review the training course. After you've used Tableau for a few months, go back and run through the training course (# 1) again. It's a great way to fill in those little gaps in your knowledge.
5) Leverage the Community. Lots of us actively blog, so read the blogs--they have so much great content. There are also a lot of people sharing their work on Tableau Public, so get an account, follow people, and when you see something interesting, download the workbook, take it apart and figure out how it works.
6) Leverage the Forums. If you have questions, ask them--we love to help. But, also, once you have your footing, come here and help to answer other people's questions. I cannot stress enough what a great way this is to learn. It forces you to deal with lots of different problems that you won't necessarily encounter in your own work.
The key thing is to keep practicing. If you're practicing, you're learning.
Agreed. I took Matt's course, based on version 9, when it was on Udemy.
I did take tableau foundation and advanced by kirill eremenko which is the best tableau course in udemy i have seen. But thanks for the suggestion. I will take a look at what you mentioned.
If you've taken some training, then you're set. The key is to just start practicing and learning from this amazing community.
Just to give you an example, my very first viz in Tableau was this map:
After one year (and a lot of time spent practicing), I created this. My point is that, by practicing and actively watching at what others are creating, you're skills (both technical and design) will improve very quickly.
cool! I see the motivation here. Thanks.
