Hi Mausumi,
Your experience of data visualisation can definitely add value to your resume. Data has become a very integral part of Consulting and clients often demand solutions driven by data, so you can add a lot of value.
For adding your points in your resume, you can use the STAR technique.
S- Express the situation for which you needed you to visualise the data
T- Briefly explain your task in the project
A - Present the actions taken by you
R - Results you were able to deliver through your data visualisation
If you are able to express your work experience in your resume through this technique, you will make a solid impact.
