About this course
Once you’ve mastered the basics of data storytelling, the next step is learning how to choose the right chart. This advanced masterclass helps finance professionals expand their chart vocabulary and sharpen their instincts so they can select the most effective visual every time.
Data storytelling trainer Olga Rudáková will guide you through the process, showing you how to grow from relying on a handful of familiar charts to confidently using around 20 essential business chart types — enough to cover almost every situation you’ll face.
You’ll explore these chart types through a real business case, following a young analyst as she works through a problem: spotting insights, choosing visuals, and building a story. Each chart will be introduced in context, the way you’ll use it in practice.
This masterclass is ideal for financial and business professionals who need to present data effectively, those communicating insights to stakeholders, and anyone simplifying complex information to deliver messages with clarity and impact.

Trainer and ConsultantOlga Rudáková
Trainer and ConsultantOlga Rudáková started as a business analyst, handing over pages of numbers to leaders… who looked puzzled. Not because they lacked insight, but because Olga didn’t yet know how to translate data into their language.
Then Olga discovered data storytelling and visualisation. Everything changed. The numbers stayed the same, but the way Olga shared them turned confusion into clarity, and clarity into action.
Since then, Olga combined their corporate finance background with public speaking and storytelling practice to help teams transform the way they work with data.
As a trainer and consultant, Olga designs and delivers interactive workshops on:
Data Storytelling – crafting clear, compelling narratives from data
Dashboard Design – building dashboards that lead to action
Olga has had the privilege to work with organizations such as Siemens, Česká Spořitelna, Johnson & Johnson, Philip Morris International, Škoda, LEGO Group, O2, T-Mobile, Albert, Takeda, AbbVie, and many more.
What Olga learned is simple: numbers don’t speak for themselves. But with the right story, they can influence decisions, inspire action, and build trust.
