The coverage visualization shows empty bar graph for nan values

[amontanez24]

Environment Details

Please indicate the following details about the environment in which you found the bug:

• SDMetrics version: diagnostic-report-properties branch
• Python version: Any
• Operating System: Any

Error Description

When examining the coverage property of the DiagnosticReport, if the score is NaN for a column, the bar graph is still made in the visualization and shows as 0. This is confusing since it didn't actually get scored and the column should just not show instead.

Steps to reproduce

from sdmetrics.reports.single_table import DiagnosticReport
from sdv.datasets.demo import download_demo
from sdv.single_table import GaussianCopulaSynthesizer

data, metadata = download_demo('single_table', 'fake_hotel_guests')
synth = GaussianCopulaSynthesizer(metadata)
synth.fit(data)
synthetic_data = synth.sample(len(data))

report = DiagnosticReport()
report.generate(data, synthetic_data, metadata.to_dict(), verbose=True)

report.get_visualization(property_name='Coverage')
