Prioritizing key design elements in an annual report can make it both engaging and easy to navigate. I once attended a seminar where we discussed how clean layouts, consistent typography, and judicious use of color can help. Visual hierarchy is crucial; headings, subheadings, and bullet points can guide the reader’s eye seamlessly through the document. Incorporating infographics and charts can very effectively convey complex data, making it digestible at a glance. In exploring this further, I found this site which might be helpful for you too. Just to add, using a consistent format for financial figures and employing ample white space can reduce visual clutter, keeping the reader focused and engaged from start to finish.
