join the Figure Friday session on September 12, at noon Eastern Time, to showcase your creation and receive feedback from the community.

“LockerNYC is a pilot program that allows New Yorkers to receive and send packages using secure lockers on public sidewalks.” What is the distribution of locker sizes in NYC?

Answer this question and a few others by using Plotly on the LockerNYC Reservations dataset.

Things to consider:

  • what can you improve in the app or sample figure below (histograms)?
  • would you like to tell a different data story using a different Dash app?
  • how can you explore the data with Plotly Studio?

Sample figure:

Code for sample figure: 
from dash import Dash, dcc
import dash_ag_grid as dag
import plotly.express as px
import pandas as pd

# download CSV sheet from Google Drive - https://drive.google.com/file/d/1EGnFTOAvYeuDd7CHajE1PdpWg-nA-IWz/view?usp=sharing
df = pd.read_csv('LockerNYC_Reservations_20250903.csv')
fig = px.histogram(df, x="Locker Size")


grid = dag.AgGrid(
    rowData=df.to_dict("records"),
    columnDefs=[{"field": i, 'filter': True, 'sortable': True} for i in df.columns],
    dashGridOptions={"pagination": True},
    # columnSize="sizeToFit"
)

app = Dash()
app.layout = [
    grid,
    dcc.Graph(figure=fig)
]


if __name__ == "__main__":
    app.run(debug=False)

For community members that would like to build the data app with Plotly Studio, but don’t have the application yet, simply go to Plotly.com/studio. Please keep in mind that Plotly Studio is still in early access.

Below is a screenshot of a scatter map built by Plotly Studio on top of this dataset:

These are just a few internet stores in Ukraine. There are many more from the major commercial delivery company (Nova Poshta) similar to FedEx/UPS. This has been available in Ukraine for a long time, but the NY initiative is interesting as it it will reduce the amount necessary, eliminating overlap. Do any other countries have these outside of the U.S.?

Good question, @mike_finko . I was wondering that as well. I’m sure they have it in other European countries as well.
