hvsampledata.earthquakes("pandas")

Tabular record of earthquake events from the USGS Earthquake Catalog that provides detailed
information including parameters such as time, location as latitude/longitude coordinates
and place name, depth, and magnitude. The dataset contains 596 events.

Note: The columns `depth_class` and `mag_class` were created by categorizing numerical values from
the `depth` and `mag` columns in the original dataset using custom-defined binning:

Depth Classification

| depth     | depth_class  |
|-----------|--------------|
| Below 70  | Shallow      |
| 70 - 300  | Intermediate |
| Above 300 | Deep         |

Magnitude Classification

| mag         | mag_class |
|-------------|-----------|
| 3.9 - <4.9  | Light     |
| 4.9 - <5.9  | Moderate  |
| 5.9 - <6.9  | Strong    |
| 6.9 - <7.9  | Major     |


Schema
------
| name        | type       | description                                                         |
|:------------|:-----------|:--------------------------------------------------------------------|
| time        | datetime   | UTC Time when the event occurred.                                   |
| lat         | float      | Decimal degrees latitude. Negative values for southern latitudes.   |
| lon         | float      | Decimal degrees longitude. Negative values for western longitudes   |
| depth       | float      | Depth of the event in kilometers.                                   |
| depth_class | category   | The depth category derived from the depth column.                   |
| mag         | float      | The magnitude for the event.                                        |
| mag_class   | category   | The magnitude category derived from the mag column.                 |
| place       | string     | Textual description of named geographic region near to the event.   |

If working in a .py file DO always serve the plot with hotreload for manual testing while developing:

```bash
panel serve path/to/file.py --dev --show

import hvplot.pandas # will add .hvplot namespace to Pandas dataframes
import hvplot.polars # will add .hvplot namespace to Polars dataframes
...

from bokeh.models.formatters import NumeralTickFormatter

df.hvplot(
    ...,
    yformatter=NumeralTickFormatter(format='0.00a'),  # Format as 1.00M, 2.50M, etc.
)

dates = pd.date_range("2022-08-01", periods=30, freq="B")

high_prices = open_prices + np.random.uniform(1, 5, size=len(dates))
low_prices = open_prices - np.random.uniform(1, 5, size=len(dates))
close_prices = open_prices + np.random.uniform(-3, 3, size=len(dates))
