+Title: '.scatter_3d()'
+Description: 'Creates a 3D scatter plot to visualize data points across three dimensions (x, y, z) with options for color, size, and hover data.'

+
+The **`.scatter_3d()`** method in the `plotly.express` module creates a 3D scatter plot to visualize the relationships between three variables using markers in a three-dimensional space. The data points are plotted based on their values on the `x`, `y`, and `z` axes. It also allows customizing marker colors, sizes, and symbols.
+
+## Syntax
+
+The `x`, `y`, and `z` parameters are required and accept values as a string, integer, `Series`, or array-like object, representing the data for each axis. Optional parameters, such as `color`, `symbol`, and `size`, customize the markers' appearance. If `data_frame` is not provided, a `DataFrame` will be constructed from other arguments.
+
+```pseudo
+plotly.express.scatter_3d(data_frame=None, x=None, y=None, z=None, color=None, symbol=None, size=None, ...)
+```
+
+- `data_frame`: The Pandas [`DataFrame`](https://www.codecademy.com/resources/docs/pandas/dataframe) containing the data to visualize.
+- `x`: The column name in `data_frame`, `Series`, or array-like object for x-axis data.
+- `y`: The column name in `data_frame`, `Series`, or array-like object for y-axis data.
+- `z`: The column name in `data_frame`, `Series`, or array-like object for z-axis data.
+- `color`: The column name in `data_frame`, `Series`, or array-like object to specify marker colors.
+- `symbol`: The column name in `data_frame`, `Series`, or array-like object for assigning marker symbols.
+- `size`: The column name in `data_frame`, `Series`, or array-like object to assign marker sizes.
+
+> **Note:** The ellipsis in the syntax (...) indicates additional optional parameters that can be used to customize the plot further.
+
+## Examples
+
+The examples below demonstrate how the [`.scatter()`](https://www.codecademy.com/resources/docs/plotly/express/scatter) method creates a 2D scatter plot, while the `.scatter_3d()` method provides a more complex visualization in three dimensions, utilizing additional parameters for color and symbol customization.
+
+### Example 1
+
+The following example demonstrates the use of the `.scatter()` method:
+
+```py
+# Defining 'x' and 'y' as array-like objects
+import plotly.express as px
+x = [1, 3, 5, 7, 9]
+y = [4, 6, 5, 8, 2]
+
+# Creating a scatter plot
+fig = px.scatter(x = x, y = y)
+
+# Displaying the plot
+fig.show()
+```
+
+The output for the above code is as follows:

+
+### Example 2
+
+This example illustrates the use of the `.scatter_3d()` method, showcasing its capability to utilize more parameters for enhanced visualization:
+
+```py
+import plotly.express as px
+
+# Sample Data
+x = [1, 3, 5, 7, 9]
+y = [4, 6, 5, 8, 2]
+z = [7, 2, 9, 4, 8]
+color = ['red', 'green', 'blue', 'purple', 'orange']
+symbol = ['circle', 'square', 'diamond', 'star', 'triangle-up']
+
+# Creating a 3D scatter plot
+fig = px.scatter_3d(x=x, y=y, z=z, color=color, symbol=symbol, title="3D Scatter Plot with Colors and Symbols")
+
+# Displaying the plot
+fig.show()
+```
+
+The above code produces the following output:
