def on_post(self, req, resp):
data = json.load(req.stream)
resp.media = {"echo": data}
app = falcon.App()
app.add_route("/echo", EchoResource())
- Using middleware for request/response processing:
import falcon
class AuthMiddleware:
def process_request(self, req, resp):
token = req.get_header("Authorization")
if token != "secret":
raise falcon.HTTPUnauthorized("Authentication required")
app = falcon.App(middleware=[AuthMiddleware()])
Getting Started
To get started with Falcon, follow these steps:
-
Install Falcon:
pip install falcon

plot = df.hvplot.scatter(x='x', y='y')
Falcon:
import plotly.graph_objects as go
import pandas as pd
df = pd.DataFrame({'x': range(10), 'y': range(10)})
fig = go.Figure(data=go.Scatter(x=df['x'], y=df['y'], mode='markers'))
Both hvplot and Falcon offer powerful data visualization capabilities, but they cater to different use cases. hvplot excels in quick data exploration and integration with the HoloViews ecosystem, while Falcon provides more interactive features and is part of the widely-used Plotly library. The choice between the two depends on specific project requirements and personal preferences.

- Fewer built-in chart types and customization options
Code Comparison
Altair:
import altair as alt
import pandas as pd
data = pd.DataFrame({'x': [1, 2, 3], 'y': [4, 5, 6]})
chart = alt.Chart(data).mark_line().encode(x='x', y='y')
Falcon:
import falcon
import pandas as pd
data = pd.DataFrame({'x': [1, 2, 3], 'y': [4, 5, 6]})
fig = falcon.line(data, x='x', y='y')
Summary
Altair offers a declarative approach to visualization, making it powerful for complex charts but potentially challenging for beginners. It excels in static visualizations and integrates well with Pandas. Falcon, on the other hand, provides a more familiar API for those coming from other plotting libraries and offers more interactive features out of the box. The choice between the two depends on the specific needs of the project and the user's familiarity with different visualization paradigms.

import matplotlib.pyplot as plt
sns.scatterplot(x="x", y="y", data=df)
plt.show()
Falcon:
import plotly.express as px
fig = px.scatter(df, x="x", y="y")
fig.show()
Key Differences
- Seaborn focuses on statistical visualizations, while Falcon (part of Plotly) offers a wider range of chart types
- Falcon provides interactive charts by default, whereas Seaborn produces static images
- Seaborn has a more consistent API for different plot types, while Falcon's API can vary depending on the chart

Falcon is a free, open-source SQL editor with inline data visualization. It currently supports connecting to RedShift, MySQL, PostgreSQL, IBM DB2, Impala, MS SQL, Oracle, SQLite and more (for connecting to Oracle, please, see here the instructions to install the required free Oracle Instant Client).
Heads up! Falcon is open source and works without an internet connection or a Plotly Chart Studio account. The software works well and we hope you find it useful. FYI, as a company we are spending most of our development effort on Dash Open Source & Dash Enterprise. Truth be told, we found that most companies we worked with preferred to own the analytical backend. With Dash, we provide the visualization and application primitives so that you can build your own tailor-made dashboards, analytical apps, or yes, even, SQL editors. If you are wondering what we're up to lately, check out our latest post on our Dash vision: Dash is bringing React to Python, R, and Julia.
