Issue: DataFrame.append() method no longer exists in newer pandas versions

Description

When using TensorWatch with recent versions of pandas (2.0+), an AttributeError is raised because the DataFrame.append() method no longer exists. This occurs in the text_vis.py file, specifically in the _append method of what appears to be a visualization class.

Error Message

AttributeError: 'DataFrame' object has no attribute 'append'

Code Location

The error occurs in the following method:

def _append(self, stream_vis, vals):
    # ... (rest of the method)
    self.df = self.df.append(self.SeriesClass(val_dict), sort=False, ignore_index=True)
    # ...

Suggested Fix

Replace all instances of self.df.append(...) with pd.concat([self.df, pd.DataFrame([...])], ignore_index=True).

For example:

self.df = pd.concat([self.df, pd.DataFrame([val_dict])], ignore_index=True)

Additional Context

• The append() method for DataFrames was deprecated in pandas 1.4.0 and removed in pandas 2.0.0.
• This change affects all users of TensorWatch who are using pandas 2.0.0 or later.

Environment

• TensorWatch version: 0.9.1
• pandas version: 2.2.2
• Python version: 3.11.9
• Operating System: Window 10

Steps to Reproduce

1. Install TensorWatch and pandas 2.0.0 or later
2. Run a script that uses TensorWatch's visualization features
3. Observe the AttributeError
