graticule.extentMajor([extent]) If extent is specified, sets the major extent of this graticule. If extent is not specified, returns the current major extent, which defaults to ⟨⟨-180°, -90° + ε⟩, ⟨180°, 90° - ε⟩⟩.

map.remove(key) If the map has an entry for the specified key string, removes the entry and returns true. Otherwise, this method does nothing and returns false.

interval(date) Alias for interval.floor. For example, timeYear(date) and timeYear.floor(date) are equivalent.

symbol.size([size]) If size is specified, sets the size to the specified function or number and returns this symbol generator. If size is not specified, returns the current size accessor, which defaults to: function size() { return 64; } Specifying the size as a function is useful for constructing a scatterplot with a size encoding. If you wish to scale the symbol to fit a given bounding box, rather than by area, try SVG’s getBBox.

d3.bisect(array, x[, lo[, hi]]) d3.bisectRight(array, x[, lo[, hi]]) Similar to bisectLeft, but returns an insertion point which comes after (to the right of) any existing entries of x in array. The returned insertion point i partitions the array into two halves so that all v <= x for v in array.slice(lo, i) for the left side and all v > x for v in array.slice(i, hi) for the right side.

d3.timeWednesdays(start, stop[, step]) d3.utcWednesdays(start, stop[, step]) Aliases for timeWednesday.range and utcWednesday.range.

d3.interval(callback[, delay[, time]]) Like timer, except the callback is invoked only every delay milliseconds; if delay is not specified, this is equivalent to timer. A suitable replacement for setInterval that is guaranteed to not run in the background. The callback is passed the elapsed time.

graticule.extentMinor([extent]) If extent is specified, sets the minor extent of this graticule. If extent is not specified, returns the current minor extent, which defaults to ⟨⟨-180°, -80° - ε⟩, ⟨180°, 80° + ε⟩⟩.

path.arcTo(x1, y1, x2, y2, radius) Draws a circular arc segment with the specified radius that starts tangent to the line between the current point and the specified point ⟨x1, y1⟩ and ends tangent to the line between the specified points ⟨x1, y1⟩ and ⟨x2, y2⟩. If the first tangent point is not equal to the current point, a straight line is drawn between the current point and the first tangent point. Equivalent to context.arcTo and uses SVG’s elliptical arc curve commands.

selection.property(name[, value]) Some HTML elements have special properties that are not addressable using attributes or styles, such as a form field’s text value and a checkbox’s checked boolean. Use this method to get or set these properties. If a value is specified, sets the property with the specified name to the specified value on selected elements. If the value is a constant, then all elements are given the same property value; otherwise, if the value is a function, then the function
