   - **Blend spine Anchor Point tool (#2544):** on a selected blend, dragging a spine corner makes symmetric Smooth handles; the tool displays and picks existing spine handles when switched to, drags one independently or retracts it on click, and clicking a point with handles retracts both. The spine is edited live without moving its key objects. Windows native canvas checks and screenshots reviewed: symmetric and independent handles, corner/retraction, Shift constraints and perpendicular reshaping, tool switching, key preservation, Undo/Redo, save/reopen, hidden handles and overlapping Path/Blend priority (PR #2643). Behaviour reference: [public path-editing documentation](https://helpx.adobe.com/illustrator/using/adjust-path-segments.html).
   - **Path editing (#494):** the handles shown are the handles that drag: Direct Selection drags those of a path selected as a whole (as the Pen leaves it), the Anchor Point tool and Pen+Alt no longer grab handles that Show handles when multiple anchors are selected hides, a handle shorter than the tolerance leaves its anchor to be picked, and the anchor tools pick within Selection & Anchor Display › Tolerance. A dragged segment keeps a smooth anchor at either end smooth. With Direct Selection, the Pen, the Curvature and the anchor tools, a path selected as a whole shows all its anchors selected, and the Control bar and the Properties panel offer Convert (corner, smooth) for them too; Remove and Cut wait for anchors direct-selected (#504). A handle drag gathers its snap targets once per drag (it took 21 ms per pointer move on a 20,000-path document, now 1 ms; `vectorcraft-cli perf` measures handle and segment drags on a 5,000-anchor path). Join merges the selected anchor points that lie on one another, as after Average, into one anchor (#1582, fixes #1533); Object › Path › Average & Join… (`path.averageJoin`, Cmd+Alt+Shift+J, the "Create corner or smooth join" shortcut of [Default keyboard shortcuts](https://helpx.adobe.com/illustrator/using/default-keyboard-shortcuts.html)) moves two open path ends to their midpoint and joins them there, a corner or smooth point as its dialog's Points choice asks, in one undo step.
-  - **Graphs:** Column, Stacked Column, Bar, Stacked Bar, Line, Area, Scatter, Pie and Radar graph tools with Graph Data and Graph Type. A series starts in greyscale; Group Selection's fill and stroke, and the paint, weight and opacity of a mark's top visible fill or stroke row after an Appearance command, the Eyedropper, a graphic style, Default Fill and Stroke or Swap Fill and Stroke, are kept separately on the graph and reapplied when its data, type or size changes, and through save, open and undo. Graph Type's Override Calculated Values (both `axisMin` and `axisMax`) uses exactly that value-axis range, split into the tick count (5 when automatic). Line graphs take Edge-to-Edge Lines (off by default: the points sit at the centres of their categories; graphs saved before the option keep their edge-to-edge lines), and radar graphs follow Mark Data Points and Connect Data Points. Blank cells (an empty CSV cell or `null`) are values left out, not zeros: columns, bars and stacked segments skip them, lines and scatter lines break around them and the value axis ignores them, while area, pie and radar draw them as 0; a number in straight quotes is a label, and the data window writes it back quoted. Graph types combine: Graph Type on series picked with Group Selection (or `series` indexes) draws them as their own type, with column, stacked column, line and area mixing on the vertical value axis and bar and stacked bar on the horizontal one; stacked columns take one slot of the cluster, lines draw in front of columns and areas behind. The value axis goes on the left, the right or both sides (column, stacked column, line, area and scatter graphs; bar graphs keep theirs along the bottom), and Separate Scales gives the series assigned to the right axis a scale of their own with its own tick values. Each value axis takes tick marks of no, short or full (across the plot) length and a count per division, and a prefix and suffix for its numbers; the category axis takes tick marks too (none by default), at or between its labels. Graph designs: Object › Graph › Design lists the designs with a preview of the selected one, and New Design (the selected art), Rename, Delete Design, Paste Design (a copy back to edit) and Select Unused, and Marker draws the data points and legend swatches of line, scatter and radar series with a design, scaled so its backmost object fills the default marker's square. Graph Data transposes rows and columns and switches a scatter graph's x and y, and a `|` in a category or series label starts a new line. Pie graphs take Legends in Wedges, Position (Even, Ratio sized by area, Stacked on one centre) and Sort (None, All, First). Graph Type takes column and cluster widths up to 1000% (overlapping past 100%) with First Row and First Column in Front (First Row orders each series' categories; across series the series order decides, so series stay one group each for Group Selection), draws filled lines, adds drop shadows behind columns, bars, lines and wedges, and puts the legend in rows across the top. Text formatted with the Character or Appearance controls, on the whole graph or on labels picked with Group Selection, is kept per kind of label (value axis numbers, category labels, legend labels) through the graph being drawn again.

   - **Graph column designs:** Object › Graph › Column (`graph.column`) draws the columns, bars or stacked segments and the legend swatch of the series picked with Group Selection with a graph design: Vertically Scaled stretches it to each column's length, Uniformly Scaled scales it both ways and centers it, Repeating stacks a copy for each Each Design Represents value and chops or scales the last one (For Fractions), and Sliding keeps the part above the design's guide line in proportion and stretches the part below. The dialog lists the designs with a preview; the choice is saved with the graph and follows the design's rename and delete.
     Type in a column design that holds a `%` followed by two digits shows each column's value in place of the `%` and the digits: the first digit is the least number of places before the decimal point (zeros are added in front; 0 gives as many as the value needs), and the second digit sets the places after it, rounded. Unless it is inside a group that clips or has its own opacity or appearance, or inside a blend, compound shape, envelope, repeat or intertwined objects, the type keeps its size and is drawn once per column in a repeating design. The legend swatch leaves it out.
