title: Pydeck tooltip format numbers
body: <p>Does anyone know how to edit the tooltip portion of a pydeck plot. Specifically, I want to change the
  <code>mrt_distance</code> in the html portion to display it in whole number, with a comma at the thousands. For example, <code>2143.45 meters</code> should be displayed as <code>2,143 meters</code>.</p>
  <pre><code>import pandas as pd
  import pydeck as pdk
  
  DATA_URL = &quot;https://raw.githubusercontent.com/ajduberstein/geo_datasets/master/housing.csv&quot;
  df = pd.read_csv(DATA_URL)
  
  view = pdk.data_utils.compute_view(df[[&quot;lng&quot;, &quot;lat&quot;]])
  view.pitch = 75
  view.bearing = 60
