KNOT LOGIC
'branch' - 1:N 'node',1:N 'node.step' and 1:N 'step'
'node' - 1:N 'node' and 1:N 'step'
'step' - 1 data-symbol
You can use flexbox shortcut attributes R (horizontal) and C (vertical) to
determine the nesting direction of 'branch'es and 'node's. (R) is optional
as horizontal is the default direction.
(Depending on orientation of the knots, all kinds of nestings might work,
but that will require trial and error, fiddling.)
SPECIFICATIONS
1) 'branch' has no specific rules, but acts as a container for 'node's
and to distinguish from 'node' and 'step'.
Add your own rules for specific 'branch' styling like fonts,colors,border,spacing.
2) 'node' and 'step' only use :before and :after to position and draw
connecting lines.
'node' horizontal line attachement
'step' vertical
'node.step' both
3) 'node.step' can be empty (no 'data-symbol'), in which case it will only
draw cross lines.
4) 'start' and 'stop' values are used to prevent drawing of
starting and ending lines.
5) Knot 'lft', 'ctr' and 'rgt' values define how sibling nodes are connected
'lft' - left hand node, only one
'ctr' - center nodes, can be more than one
'rgt' - right hand node, only one
My motivation for use of 'data-* attributes' instead of classes is they
are easy accessible as javascript variables:
someElement.dataset.chart
someElement.dataset.knot
someElement.dataset.symbol

ALGEBRA for responsive sizing
ALL responsive sizes in this document use the 'point-slope' variation
of the 'definition of a straight line: y=mx+b':
(https://www.mathsisfun.com/algebra/line-equation-point-slope.html)
y - y1 = y1 + m(x - x1) <=> y = y1 + m(x - x1)
For points:
p1 = (x1,y1) - size at minimum viewport size (x1 default 320px)
p2 = (x2,y2) - size at maximum viewport size (x2 default 1280px)
(using 320px and 1280px will create a full step each 160px)
where:
m = (y2 - y1) / (x2 - x1) ('Slope')
x = fixed value of 100vmin, 100vh or 100vw ('X-intercept')
b = y1 - (m * x1) ('Y-intercept')
X-axis = viewport size
Y-axis = element size
Substituted equation to use:
y = y1 + (y2 - y1) / (x2 - x1) * (x - x1)
NOTES
- Use VMIN for viewport width/height independed results (like fonts)
- Use VW/VH for viewport width/height dependend results (width,height,margin,padding)
- Do not use VMAX for x, it will yield results that are to large.
