A horizontal timeline chart titled “Viz-ibly, we’ve come a long way: The evolution of maps, graphs and data visualisation,” spanning from 6000 BC to the 2000s. Events are grouped into four rows: Cartography, Statistics & Graphics, Technology, and Other. In Cartography, milestones are marked such as first known map (6200 BC), first world map (550 BC), latitude/longitude (90 AD), cylindrical projection (1569), first modern atlas (1570), choropleth maps (1819, 1826), London Underground map (1933), GIS (1960), and early weather and disease maps. In Statistics & Graphics, markers include early star charts and Earth measurements (240–134 BC), planetary diagrams (950), first data graph (1644), bar and line graphs (1786), pie chart (1801), mortality curves (1828), age pyramid (1874), and later methods like Chernoff faces, treemaps, parallel coordinates, ISOTYPE, Grammar of Graphics, and Gapminder. In Technology, markers include parchment (170 BC), paper (105 AD), movable type (1453), graph paper (1794), lithography (1798), first photograph (1827), first digital computer (1944), Fortran (1957), and S language (1978). In Other, milestones include color system diagrams (1758), periodic table (1869), and fisheye view (1981).
#Day19: Evolution
Tried a chart about the evolution of charts! Centuries of trying to understand the world through data and graphics visualised.
