  title: Microsoft Excel Build a Chart from a Data Range
  summary: Verify a source range has data, create a chart over it, and confirm the chart exists.
  description: >-
    Turning a block of numbers into a visual is the payoff step of most Excel
    reporting integrations. Charts in the Graph Excel API are created against a
    source data range, so this flow reads that range first to prove it is
    populated and correctly sized before a chart is built over it, lists the
    charts already on the sheet to avoid stacking duplicates, adds the chart,
    and lists the charts again to confirm. Every step spells out its request
    inline so the flow can be read and executed without opening the underlying
    OpenAPI.

  summary: Create a chart over a verified source range and confirm it was added.
  description: >-
    Reads and validates the source data range, checks the worksheet's existing
    charts, adds a new chart of the requested type, and verifies the result.
  inputs:
    type: object
    required:
    - itemId
    - worksheetIdOrName
    - sourceData
    - chartType
    properties:
      itemId:
        type: string
        description: The drive item id of the workbook file.
      worksheetIdOrName:
        type: string
        description: The worksheet the chart is drawn on.
      sourceData:
        type: string
        description: >-
          The A1-notation range the chart plots, including the header row
          (e.g. "A1:C4").
      chartType:
        type: string
        description: >-
          The Excel chart type to create (e.g. "ColumnClustered", "Line",
          "Pie").
  steps:
  - stepId: openSession
    description: Open a persisting session so the created chart is saved to the stored workbook.
    operationId: createWorkbookSession
    parameters:
    - name: item-id
      in: path
      value: $inputs.itemId
    requestBody:
      contentType: application/json

    successCriteria:

    outputs:
      sessionId: $response.body#/id
  - stepId: verifySourceData
    description: >-
      Read the source range before charting it. A chart built over an empty or
      wrongly sized range renders blank, and this read catches that early.
    operationId: getRange
    parameters:
    - name: item-id
      in: path
      value: $inputs.itemId
    - name: worksheet-id-or-name

      value: $inputs.worksheetIdOrName

  - stepId: listExistingCharts
    description: >-
      List the charts already on the worksheet so a repeated run can be
      recognised instead of stacking a second chart on top of the first.
    operationId: listCharts

      Create the chart over the verified range. seriesby Auto lets Excel decide
      whether the series run by row or by column based on the range shape.

  - stepId: verifyChart
    description: >-
      List the charts again to confirm the new chart is present on the sheet and
      to hand the caller the full chart set with positions.
