Calculates axis-aware plot area bounds

SyntaxExampleDefinition

DaxLib.SVG.Axes.Layout( x, y, width, height, maxTickLabelWidth, showAxis, axisFontSize )

Parameter	Type	Default	Description
x	NUMERIC VAL		Content x
y	NUMERIC VAL		Content y
width	NUMERIC VAL		Content width
height	NUMERIC VAL		Content height
maxTickLabelWidth	NUMERIC VAL		Estimated max y-label width
showAxis	BOOLEAN	`FALSE()`	Optional: Whether axes are enabled. Defaults to FALSE
axisFontSize	INT64	`10`	Optional: Axis font size. Defaults to 10

TABLE Single-row table with @PlotX, @PlotY, @PlotWidth, @PlotHeight

// Returns single-row table:
//   @PlotX     – left edge of plot area (after Y-axis reservation)
//   @PlotY     – top edge of plot area (after top padding)
//   @PlotWidth – available plot width
//   @PlotHeight – available plot height
