The function correlation_plot in the module hana_ml.visualizers.eda_plotly displays a correlation plot for specified columns of a SAP HANA DataFrame, with options to customize the ID column, columns to be plotted, color scale, and title of the plot.
------
Here is the executable code template for the `correlation_plot` function:

```python
from hana_ml.visualizers.eda_plotly import correlation_plot

# Assuming `data` is your DataFrame
data = ...

# Specify the columns you want to plot
corr_cols = ['PCLASS', 'AGE', 'SIBSP', 'PARCH', 'FARE']

# Call the function
fig, corr = correlation_plot(data=data, corr_cols=corr_cols)

# Display the plot
fig.show()
```

Please replace `...` with your actual DataFrame. If you want to use different columns, replace the list assigned to `corr_cols`. You can also customize the color scale and title by providing values for `cmap` and `title` parameters respectively.
