What Is Dash?
What Is Dash? 관련
Dash is an open-source framework for building data visualization interfaces. Released in 2017 as a Python library, it’s grown to include implementations for R, Julia, and F#. Dash helps data scientists build analytical web applications without requiring advanced web development knowledge.
Three technologies constitute the core of Dash:
- Flask supplies the web server functionality.
- React.js renders the user interface of the web page.
- Plotly.js generates the charts used in your application.
But you don’t have to worry about making all these technologies work together. Dash will do that for you. You just need to write Python, R, Julia, or F# and sprinkle in a bit of CSS.
Plotly, a Canada-based company, built Dash and supports its development. You may know the company from the popular graphing libraries that share its name. The company released Dash as open source under an MIT license, so you can use Dash at no cost.
Plotly also offers a commercial companion to Dash called Dash Enterprise. This paid service provides companies with support services such as hosting, deploying, and handling authentication on Dash applications. But these features live outside of Dash’s open-source ecosystem.
Dash will help you build dashboards quickly. If you’re used to analyzing data or building data visualizations using Python, then Dash will be a useful addition to your toolbox. Here are a few examples of what you can make with Dash:
- A dashboard showing object detection for self-driving cars
- A visualization of millions of Uber rides
- An interactive tool for analyzing soccer match data
This is just a tiny sample. If you’d like to see other interesting use cases, then go check out the Dash App Gallery.
Note
You don’t need advanced knowledge of web development to follow this tutorial, but some familiarity with HTML and CSS won’t hurt.
You should know the basics of the following topics, though:
- Python graphing libraries such as Plotly, Bokeh, and Matplotlib
- HTML and the structure of an HTML file
- CSS and style sheets
