 ### Updated
-- Updated Plotly.js from version 2.24.1 to version 2.24.2. See the [plotly.js CHANGELOG](https://github.com/plotly/plotly.js/blob/master/CHANGELOG.md#2242----2023-06-09) for more information. These changes are reflected in the auto-generated `plotly.graph_objects` module.

See the [plotly.js CHANGELOG](https://github.com/plotly/plotly.js/blob/master/CHANGELOG.md#2252----2023-08-11) for more information. These changes are reflected in the auto-generated `plotly.graph_objects` module. Notable changes include:
+  -  Add "Equal Earth" projection to geo subplots [[#6670](https://github.com/plotly/plotly.js/pull/6670)],
+   with thanks to @apparebit for the contribution!
+  - Add options to include legends for shapes and `newshape` [[#6653](https://github.com/plotly/plotly.js/pull/6653)]
 - `px` methods now accept data-frame-like objects that support a [dataframe interchange protocol](https://data-apis.org/dataframe-protocol/latest/index.html), such as polars, vaex, modin etc. This protocol has priority on `to_pandas` call, but will only be used if pandas>=2.0.2 is installed in the environment.
+- `px` methods now accept data-frame-like objects that support a `toPandas()` method, such as Spark DataFrames, or a `to_pandas_df()` method, such as Vaex DataFrames.

 ### Trace Types, Legends and Color Bars
 
-[Traces](/python/figure-structure) of most types can be optionally associated with a single legend item in the [legend](/python/legend/). Whether or not a given trace appears in the legend is controlled via the `showlegend` attribute. Traces which are their own subplots (see above) do not support this, with the exception of traces of type `pie` and `funnelarea` for which every distinct color represented in the trace gets a separate legend item. Users may show or hide traces by clicking or double-clicking on their associated legend item. Traces that support legend items also support the `legendgroup` attribute, and all traces with the same legend group are treated the same way during click/double-click interactions.

Traces that support legend items and shapes also support the `legendgroup` attribute, and all traces and shapes with the same legend group are treated the same way during click/double-click interactions.
 
 The fact that legend items are linked to traces means that when using [discrete color](/python/discrete-color/), a figure must have one trace per color in order to get a meaningful legend. [Plotly Express has robust support for discrete color](/python/discrete-color/) to make this easy.

-The `legendrank` attribute of a trace can be used to control its placement within the legend, without regard for its placement in the `data` list.
+If you have shapes that are configured to appear in a legend, these are displayed after all traces:
 
-The default `legendrank` for traces is 1000 and ties are broken as described above, meaning that any trace can be pulled up to the top if it is the only one with a legend rank less than 1000 and pushed to the bottom if it is the only one with a rank greater than 1000.

+
+The `legendrank` attribute of a trace or shape can be used to control its placement in the legend.
+The default `legendrank` for traces and shapes is 1000. When all traces and shapes have the same `legendrank`, traces appear in the order they appear in the data, followed by shapes in the order they are defined.
+
+Any trace or shape can be pulled up to the top of the legend if it is the only one with a legend rank less than 1000 and pushed to the bottom if it is the only one with a rank greater than 1000.
+
+In this example, we add a `legendrank` for each trace and shape, giving the shape the lowest rank so it appears first, and moving the first trace defined to the bottom of the legend by giving it the highest rank.
