Sankey Diagram illustration: a diagram shows an example of the flow of materials in a system. The example illustrated is the point of disposing of domestic waste. The jumbled, inbound mix of waste brought in on the left gets separated into outbound flows on the right including card recycling; plastic, glass & metal recycling; compost; landfill and directly re-useable items (such as milk bottles). The width of each outbound arrow represents size of flow. Sankey diagramThe Keeling Curve illustration: A line graph shows a tight zig-zag red line rising from around 310 parts per million (ppm) monthly average CO2 concentration in the air at the top of Mauna Loa volcano in Hawaii in 1960, up to 410 ppm in 2020. The smaller graph at the top shows the reason for the zig-zag nature of the line; the seasonal variation of CO2 concentration in the air due to more plants blooming and photosynthesising in Spring and Summer. The Keeling curveA little bit of slope makes up for a lot of Y-intercept illustration: on a line graph, a red line starts well below the blue line, but over time, it overtakes and surpasses the blue line because it has slightly more gradient to it. A little bit of slope makes up for a lot of y-intercept.What is Metcalfe's Law diagram the value of a network and its usersMetcalfe’s LawIsochrones illustration: An aerial view of London shows enclosed concentric, but irregular shapes, radiating out from the centre of the city, denoting areas of equal travel time; from 5 minutes to 30 minutes.

Instead of one large release, a series of smaller software updates each with smaller, more manageable risk is suggested.
