Pixels or Perish The art of scientific illustration will have to
adapt to the new age of online publishing At the heart of the D3
framework is a simple but general mechanism for creating or
modifying elements of the DOM based on supplied data. For
example, in the pyramid figure, the length of each bar is
determined by an entry in a table that lists population by age,
gender and year. When the year changes, each bar length is
relinked to a different entry in the table. The updating of the
display and the animated transitions are handled behind the
scenes by the D3 library. In designing my population pyramid I
was inspired by several examples and tutorials on the D3 website
(https://github.com/mbostock/d3/wiki) and I borrowed snippets of
code from them. There are at least two more population pyramids
among the examples, and many other delightful tools and toys
worth exploring. » Post Comment
