I’m very excited to share a Python Dash dashboard showcasing a mock-data visualization of a COVID-19 SEIR interventions model. SEIR models provide insight into epidemiological dynamics.

The dashboard allows users to tweak model parameters and visualize the resulting COVID-19 hospitalization, death rate, and daily cases.

Dash Application: [https://intervention-model.herokuapp.com/](https://intervention-model.herokuapp.com/)

As part of a proof of concept for a customer, we were tasked with recreating Healthcare Coalition’s R-Shiny dashboard into a Dash app with serious time constraints. In just 1.5 weeks we reproduced the entire dashboard achieving parity with all the key features:

- Charts and controls for decision-makers to interact with their COVID-19 model
- Toggleable sidebar and panels to save precious screen real estate
- Written exclusively in Plotly’s Dash and Dash Design Kit
- A mobile-friendly experience

Matthew, this app looks amazing. Is the toggleable sidebar based on the ddk.Sidebar component?
