Companies today collect a lot of data, and it's usually hard to make sense of all of it. This data needs to be presented in a way so that anyone in the company can find what they need to push the business forward. It can answer many questions and help a company grow if presented in the right way to the right people.

“Numbers have an important story to tell. They rely on you to give them a clear and convincing voice.”
―Stephen Few

Our next guest is Milena Petrović, who is working as a Business Intelligence Developer at TNation. She says a picture is worth a thousand words, and even more in data science. She covers the topic of data visualization and touches on the topic of women in data science. Check out the full interview below and hear what she has to say.



Visualizing data can be challenging and one must know the people they are presenting it to, in order to make it as clear as possible. Data visualizations are often made interactive so that their end users can see what they need at the moment - just the details or the entire picture at once. She says she doesn’t see herself as an artist since every visualisation that is create must be useful in order to fulfill its purpose and if there’s room for it, it’s made beautiful as well.

Differences in data consumption preference among countries

Our interviewee has worked in many international companies and when asked if there are differences in how different countries consume their data, she sad there are. Some countries like their data drilled down to every detail because they seem to think that something is being hid if they don’t see every part of it. Others seem to like to look at the big picture first and then decide to which level of detail they want to explore.

Why shouldn’t women be data scientists?

There aren’t many reasons a women shouldn’t be a data scientist, although Milena remembered one - women can get too detail oriented and it can be harder for them then for men. Nonetheless, she excludes herself from this category and says you just need to find what works best for you. So it’s an individual thing, not a gender one.

Advice for girls who dream of doing data visualisation

“The greatest value of a picture is when it forces us to notice what we never expected to see.”

―John Tukey

In a world full of possibilities the only thing you need is persistence and you will get almost anything you want! Be ambitious and don’t give up on your goals is what Milena advises. Furthermore, she says that education is clearly important as well as the actual knowledge you possess and that’s something no one can take away from you wherever you go.
