As the graphs and tables show, these can be coordinated with company colourways and the theme can be extended to the cover page along with insertion of logos. Pictures and graphics that add value in terms of understanding to the plan can also be embedded in the document.
Please note it is important to not apply graphics and photos to the plan which are general and do not relate to the content of the plan. Investors dislike spending time understanding a generic graphic, simply to find out that it is irrelevant, even if it is ascetically pleasing. Contrary to common belief this sort of approach turns the plan into an amateur piece of work as opposed to making it look more professional.
