Understanding the target audience is crucial because different users have varying levels of data literacy and unique needs. A data visualization consultant designed for data scientists might include complex metrics and detailed breakdowns, while a dashboard for executives should focus on high-level KPIs and trends. Knowing the audience’s familiarity with the data helps a consultant choose the appropriate level of detail and complexity. Understanding their decision-making processes allows for tailored recommendations. A well-designed visualization resonates with the audience, ensuring they can interpret the data effectively and make informed decisions.
