How will data analytics (especially data visualization) evolve over the next 10 years? Will we still be using Tableau and Power BI dashboards in 10 years? If so, how will they be different? Or will they be replaced by something new?

Analytics capabilities will improve dramatically in the next 3 years, so significant changes to visualization will come much sooner than 10 years. Analytics is in the process of maturing from descriptive models to diagnostic, predictive, and prescriptive models. Those are more reliable. They extend the time horizon that businesses can see and the complexity of the systems that can be understood.

Simple data visualizations fit the descriptive model paradigm but not what comes next. In many cases, users will not have enough context to know which questions are most important to ask, what options are available, or what data is most relevant to their decisions.

In response, data visualization will include that context and metadata. It will support the user when they need it instead of waiting for the user to initiate the data request. Visualization will reduce the complexity of interacting with data to make better decisions.

I'm hopefull and interested in combining LLM and visualisation tools... I imagine it like having my own personal data visualisation specialist that I can just endlessly ask to make things exactly like I would like them (that may be the perfectionist in me speaking). But getting past "having to know all the buttons and checkboxes in the tool" to create the visualisation you were looking for sounds like a great idea.
