this infographic has chronology of 23 years: i tried to fit on the page but i decided to move it to another infographic for practical considerations. for example, the size had to be a3/a2/a1 for the convenience it affords to be printed anywhere. i chose the timeline to be 63 years, and the space around the last 23 years would be crowded, as most recorded events are in this period. hence it was decided, to move it to another infographic and retain only the most important milestones. the other issue was about keeping the background white, instead of parchment or a faded masjid nabawi pic (which makes it even more noisy and difficult to read). but the layout of the turkish infog is nice; not surprising, as he is a professional artist.
