Amazon QuickSight introduces pixel-based font sizing for Textbox, a departure from the fixed font sizes ranging from small to X-large. This enhancement empowers authors with unmatched precision, allowing them to finely adjust font sizes based on numeric or pixel values ("14px" or "32px"), granting greater flexibility. Along with this we are also adding text highlighting capabilities, similar to that of Insights visual. You can highlight text to emphasis key data points and insights making it easier to drive user attention precisely where you want it, making your data-driven narratives even more compelling.
