==== Quantitative Scales ====
Map a continuous (numeric) domain to a continuous range
 * linear
 * sqrt
 * pow
 * log
 * quantize
 * threshold
 * quantile
 * identity

{{{#!c
var x = d3.scale.linear()
    .domain([12, 24])
    .range([0, 720]);
x(16); // 240
}}}

{{{#!c
var x = d3.scale.sqrt()
    .domain([12, 24])
    .range([0, 720]);
x(16); // 268.9056992603583
}}}

{{{#!c
var x = d3.scale.log()
    .domain([12, 24])

==== Domains & Ranges
{{{#!c
var x d3.scale.linear()
    .domain([0, d3.max(numbers)])
    .range([0, 720]);
}}}

{{{#!c
var x d3.scale.log()
    .domain(d3.extent(number))
    .range([0, 720]);
}}}

{{{#!c
function value(d) { return d.value; }
var x d3.scale.log()
    .domain(d3.extent(object, value))
    .range([0, 720]);
