          columns
              The number of columns in the grid. If you provide a 2D
              `subplots` array, the length of its longest row is used
              as the default. If you give an `xaxes` array, its
              length is used as the default. But it's also possible
              to have a different length, if you want to leave a row
              at the end for non-cartesian subplots.
          domain
              :class:`plotly.graph_objects.layout.grid.Domain`
              instance or dict with compatible properties
          pattern
              If no `subplots`, `xaxes`, or `yaxes` are given but we
              do have `rows` and `columns`, we can generate defaults
              using consecutive axis IDs, in two ways: "coupled"
              gives one x axis per column and one y axis per row.
              "independent" uses a new xy pair for each cell, left-
              to-right across each row then iterating rows according
              to `roworder`.
          roworder
              Is the first row the top or the bottom? Note that
              columns are always enumerated from left to right.
          rows
              The number of rows in the grid. If you provide a 2D
              `subplots` array or a `yaxes` array, its length is used
              as the default. But it's also possible to have a
              different length, if you want to leave a row at the end
              for non-cartesian subplots.
          subplots
              Used for freeform grids, where some axes may be shared
              across subplots but others are not. Each entry should
              be a cartesian subplot id, like "xy" or "x3y2", or ""
              to leave that cell empty. You may reuse x axes within
              the same column, and y axes within the same row. Non-
              cartesian subplots and traces that support `domain` can
              place themselves in this grid separately using the
              `gridcell` attribute.
          xaxes
              Used with `yaxes` when the x and y axes are shared
              across columns and rows. Each entry should be an x axis
              id like "x", "x2", etc., or "" to not put an x axis in
              that column. Entries other than "" must be unique.
              Ignored if `subplots` is present. If missing but
              `yaxes` is present, will generate consecutive IDs.
          xgap
              Horizontal space between grid cells, expressed as a
              fraction of the total width available to one cell.
              Defaults to 0.1 for coupled-axes grids and 0.2 for
              independent grids.
          xside
              Sets where the x axis labels and titles go. "bottom"
              means the very bottom of the grid. "bottom plot" is the
              lowest plot that each x axis is used in. "top" and "top
              plot" are similar.
          yaxes
              Used with `yaxes` when the x and y axes are shared
              across columns and rows. Each entry should be an y axis
              id like "y", "y2", etc., or "" to not put a y axis in
              that row. Entries other than "" must be unique. Ignored
              if `subplots` is present. If missing but `xaxes` is
              present, will generate consecutive IDs.
          ygap
              Vertical space between grid cells, expressed as a
              fraction of the total height available to one cell.
              Defaults to 0.1 for coupled-axes grids and 0.3 for
              independent grids.
          yside
              Sets where the y axis labels and titles go. "left"
              means the very left edge of the grid. *left plot* is
              the leftmost plot that each y axis is used in. "right"
              and *right plot* are similar.
