    the inspiration!

    Fix `d3_array` for older/more esoteric browsers.

    jasondavies authored
    This code is adapted from `makeArray` in Sizzle.js.
Commits on Feb 17, 2011
  1. Support for Sizzle.

    authored
    D3 now supports Sizzle, preferring Sizzle to the native Selectors API if Sizzle
    is available. Sizzle internally uses the native Selectors API and thus this
    should have minimal performance implications; also, it allows you to use Sizzle
    proprietary extensions such as ":first".
    
    This commit also restricts the definition of the enter selection so that only
    append and insert operations are defined. The other operations were generally
    unsupported anyway, and it cleans up the code to have separate implementations
    for insert and append. (I might enable additional operations in the future, such
    as `filter`, `sort` and `each`, but this seems like a reasonable first pass.)

  1. Add support for namespaced listeners.

    authored
    You can now also remove listeners by specifying a null listener.

  1. Add d3.svg.symbol.

    authored
    The `symbol` class can be used to generate dot symbols for scatterplots. This
    commit also fixes a couple bugs with negative-domain log and pow scales, as well
    as tick generation.

  1. Add d3.geo.bounds.

    authored
    This method can be used for computing the bounding box of arbitrary GeoJSON
    objects. This commit also fixes a bug in d3.geo.path, such that it will accept
    any GeoJSON object, rather than requiring GeoJSON feature objects.
  2. Add color-by-area with zoom example.

    authored
    This uses d3.geo.path to compute the projected area (in square pixels) of each
    county in the choropleth. It also usees d3.behavior.zoom to add geometric pan
    and zoom.
Commits on Feb 11, 2011
  1. Add d3.behavior module.

    authored
    Includes, as the first behavior, a pan & zoom behavior. The canvas can be panned
    by dragging the mouse, and zoomed using the mousewheel (or by double-click). By
    listening to redraw events, users can decide whether to implement geometric
    zooming (such as by setting the "transform" attribute on an `svg:g` element) or
    semantic zooming (by changing the domain of a scale object and repositioning
    elements).
    
    This commit also includes two bug fixes. The `d3.format` class now properly
    groups thousands of negative numbers, and supports the sign specifier. The
    unicode minus symbol \u2212 is used for negative values. The `d3.scale.pow`
    class now properly handles negative numbers, as well.

  1. Fix two bugs in transitions.

    authored
    First, always coerce the tween target value (the value of the style or attribute
    at the end of the transition) to a string. This guarantees that the correct
    interpolator is chosen, and avoids a null dereference.
    
    Second, default color channels to zero rather than undefined, so as to avoid NaN
    channel values if there is an error parsing the color. This can occur, say, if
    the background color of a div is unset and defaults to "rgba(0, 0, 0, 0)".

  1. Don't use the null context.

    authored
    Instead, use the group data array as the context when evaluating the join key
    function on the new data.

  1. Simplify data join. Add insert & empty.

    authored
    The data join is now specified as a single function of data, as with all other
    properties. This allows the key to be computed on the previously-bound data,
    rather than requiring the key to be serialized into the DOM (say, as an
    attribute). In the case that there is no previously-bound data, it is still
    possible to access the associated node as the `this` context.
    
    The `enter` operator no longer performs an append. For symmetry with the `exit`
    operator, you must call `append` after obtaining the entering selection. This
    requires a tiny bit more code, but should make the code more clear. Also, it
    provides an opportunity to use a different instantiation operator, such as the
    new `insert` operator. This takes a second argument, which is a selector for the
    insert-before reference element. For example, the selector ":first-child" will
    prepend nodes.
    
    The `empty` operator allows you to query whether a selection is empty (i.e.,
    contains zero matching nodes).
  2. Restructure calendar example.

  1. Fix Firefox bug with style transitions.

    authored
    You can't set the priority to be undefined; it has to be null. (Even though
    null == undefined in JavaScript, but let's not be picky!)

  1. Scale interpolators & range rounding.

    authored
    You can now override the scale interpolator by calling the `interpolate` method.
    One particularly useful interpolator is the new `d3.interpolateRound`, which is
    like `interpolateNumber`, except that it returns integers. This makes it easier
    to produce a scale that outputs exact pixel values, and avoid antialiasing
    artifacts.
    
    For convenience, the quantitative scales have a `rangeRound` method which sets
    the range and the interpolator at the same time. Similarly, a `rangeRoundBands`
    has been added to the ordinal scale.

  1. Add d3.scale.quantize.

    authored
    A quantize scale is much like a linear scale, but it returns a discrete value
    from a set range (similar to quantile and ordinal scales).
