*TRANSFORM A CURVE USING A DATASET CONTAINING THE OPERATIONS*
=============================================================

Applies a sequence of mathematical transformations to a curve, where the operations are defined in a structured dataset (columns: id, type, args). Use this worker when the transformation pipeline is dynamic or data-driven and needs to be specified externally rather than hard-coded in the workflow.

When to use
-----------

Classification: **process**.

Tagged: ``batch``, ``curve``, ``dataset-driven``, ``operations``, ``pipeline``, ``transform``.

Inputs
------

.. list-table::
   :header-rows: 1
   :widths: 20 20 20 20 20 20

   * - Label
     - ID
     - Type
     - Default
     - Required
     - Description
   * - Curve
     - curve
     - vector
     - —
     - 
     - The input curve (X/Y vector pair) to be transformed; accepts any d3VIEW curve object — see the Curve Input glossary for supported formats.
   * - Transformations
     - transformations
     - dataset
     - —
     - 
     - Dataset table defining the ordered transformation pipeline; must contain exactly three columns — 'id' (row identifier), 'type' (transformation name, e.g. scale, offset, slice), and 'args' (comma-separated or JSON arguments for that operation).
   * - Parameters
     - parameters
     - keyvalue
     - —
     - 
     - Optional key-value map of named parameters whose values can be referenced by name inside the 'args' column of the transformations dataset, enabling reusable parameterised pipelines.

Outputs
