To meet user requests for a pie chart, which technique should a business analyst use?

Choosing to create a custom theme for a pie chart allows a business analyst to tailor the visual representation of data precisely to the preferences and branding requirements of the organization or the audience. Custom themes provide flexibility in terms of color schemes, font styles, and other visual elements, ensuring that the pie chart not only presents data effectively but also aligns with the overall aesthetic of the application or report.

Creating a custom theme would be particularly beneficial when standard styles do not adequately meet user requests or when a unique visual style is desired to enhance user engagement. This allows for a cohesive look across various reports and dashboards, contributing to a better user experience and clearer data communication.

In contrast, using a default style template might restrict the ability to customize colors and styles to fit specific requirements, and modifying the existing color scheme in the chart properties would be limited to that particular chart rather than providing a broad, consistent theme across multiple visualizations. Creating a new data model would be unnecessary for simply adjusting the visual aspects of a chart, as it pertains more to data structuring rather than presentation.
