TypeError: barh() got multiple values for argument 'width'

This error occurs when the `barh()` function in Matplotlib is called with more than one argument for the `width` parameter. The `width` parameter specifies the width of the bars in a horizontal bar chart.

Here's an example of how this error can occur:

import matplotlib.pyplot as plt

x = [1, 2, 3]
y = [4, 5, 6]

plt.barh(x, y, width=0.5, width=0.3)

In this example, the `barh()` function is called with two values for the `width` parameter (`0.5` and `0.3`). This causes the `TypeError` to be raised.

To fix this error, simply remove the extra argument for the `width` parameter:

import matplotlib.pyplot as plt

x = [1, 2, 3]
y = [4, 5, 6]

plt.barh(x, y, width=0.5)

In this fixed example, the `barh()` function is called with only one value for the `width` parameter (`0.5`).
