Pictorial representation is one species of visual representation.” – John Dilworth (varieties of visual presentation)
3. 3. METHODS OF VISUAL PRESENTATIONS Tabulated data Maps Line Graphs Cartograms Bar Graphs Flow charts Gantt Charts Visual Planning Boards Pie Charts Computer Graphics Pictograms
4. 4. TABULATED DATA Tabulated data is data that has been sorted, organized and represented in a tabular form. Use of tabulated data: Tabulated data is used when a heavy amount data needs to be accessed and analyzed at a glance.
5. 5. EXAMPLE OF TABULATED DATA

18. 18. PIE CHARTS A pie chart (or a circle graph) is a circular chart divided into sectors, illustrating proportion.. Use of Pie charts: Pie charts are good at showing the comparative sizes of multiple objects.
19. 19. EXAMPLE OF A PIE CHARTS
20. 20. CARTOGRAMS  A cartogram is a map in which some thematic mapping variable – such as travel time or Gross National Product – is substituted for land area or distance.  Geometry or space of the map is distorted in order to convey the information of this alternate variable  Main types of cartograms: area and distance cartograms  A distance cartogram is used to show relative travel times and directions from vertices in a network.
21. 21. EXAMPLE OF A CARTOGRAM

If you have to say "I know you can't read this but.....," why include the visual at all? One popular rule of thumb is the "8H" rule of legibility. In a nutshell, if you can read an image from eight times its height, odds are your audience will be able to read it when projected
