Tag Archives: Data Visualization
this blog post is to introduce open source business intelligence technologies and explore data using open source technologies like D3.js, DC.js, Nodejs and MongoDB.
Over the span of this post we will see the importance of the various components that we are using and we will do some code based customization as well.
The following should be an introduction to combining D3 with React to create reusable chart components. This is not intended to be an introduction into D3 nor React, there is a large number of resources to help getting off the ground with either frameworks, for example this for D3 and this for React.
D3s approach to data visualization fits well with the React way of building UI components and App structuring. React encourages to figure out how to structure a number of components to enforce a data flow that moves from top down, meaning that lower level components receive data and render it at best and only keep state if needed, but never manipulating any data that might affect the higher up components.
Another strong correlation between the libraries is their respective component lifecycle. D3 has enter,update and exit.
React has componentWillUpdate, componentDidUpdate and componentWillUnmount, enabling us to map the D3 lifecycle directly to the React one.
The following is just an experiment to see how far we can replace the D3 rendering with React.
Learn the basics of data visualization and charts to present data sets on the web with no programming. Kristian Allen from the Digital Library Program at UCLA Library will cover the proper format to structure your data for use with common web tools and review some popular charting and visualization frameworks available, including Google Charts and Fusion tables.
Data visualization has become a more frequent element of our work at Viget. Be it simple pie charts or beautiful maps displaying jersey sales, visually representing data in a compelling way is a great device for storytelling and provides rich fuel for social sharing.
Yet making these illustrations fast, shareable, and accessible has its challenges. Although browsers are powerful, tightly coupling the rendering process to them greatly complicates the generation of images that can be shared or saved for presentations.
The conference is over, but the conversation has just begun.
Mihai Parparita detailed his efforts to hack his way to a React.js Conf ticket; James Longblogged about his first encounter with React Native; Eric Florenzano talked about how he perceives the impact of Relay, GraphQL, and React Native on software development;Margaret Staples blogged about her experience of being on-campus at Facebook HQ; Jeff Barczewski tied his experience of attending the conference up with a bow in this blog post filled with photos, videos, and links; Kevin Old left us with his takeaways; Paul Wittmannfound React Native freshly on his radar; and finally, undeterred by not being able to attend the conference in person, Justin Ball summarized it from afar.
Tom Occhino opened with a history of how React came to be, before announcing Facebook’s answer to a long-looming what-if question: what if we could use React to target something other than the DOM?
Tweaking in real time
Brenton Simpson showed us how eBay brings Bret Victor’s feedback loop to your favorite editor using Webpack, react-hot-loader, and Ambidex.
Abstract Syntax Trees
Gurdas Nijor showed us how we can leverage some conventions of React to perform source code transformations that unlock an inspirational set of use cases.
Relay and GraphQL
Daniel Schafer and Jing Chen showed us how Facebook approaches data fetching with React, giving us an early peek at the forthcoming duo of Relay and GraphQL.
James Long explores what might happen if we introduce channels, a new style of coordinating actions, to React.
Michael Jackson reminded us that URLs should be part of our design process, and showed us how react-router can help to manage the transitions between them.
Pete Hunt showed us how a Flux approach can help us scale actions and questions on the backend in addition to the frontend.
Jason Bonta showed us how complex user interfaces can get, and how his team keeps them performant as they scale. He also had the pleasure of open-sourcing his team’s work on FixedDataTable.
FormatJS and react-intl
Eric Ferraiuolo showed how you can bring your app to a worldwide audience using a series of polyfills and emerging ECMAScript APIs.
Ryan Florence showed us how easy it is to transition from a career selling life insurance, to a burgeoning one as a software developer. All you have to do is to learn how to say “yes.”
Christopher Chedeau showed us how to bring the developer experience of working with React on the web to native app development, using React Native.
Andrew Rota explained how React and Web Components can work together, and how to avoid some common pitfalls.
Beyond the DOM
Jafar Husain told us a story about how Netflix was able to push React into places where the DOM could not go.
Zach Nation showed us how we can produce visualizations from over 45 million data points without breaking a sweat.
Bill Fisher coordinated a Flux panel together with Michael Ridgway, Spike Brehm, Andres Suarez, Jing Chen, Ian Obermiller, and Kyle Davis.
Bonnie Eisenman led us through the ‘adapter’ approach to inter-component communication taken by her team at Codecademy.
Flow and TypeScript
James Brantly demonstrated how we can reap the benefits of static typing using both Flow and TypeScript.
Core Team Q&A
Tom Occhino, Ben Alpert, Lee Byron,Christopher Chedeau, Sebastian Markbåge, Jing Chen, and Dan Schaferclosed the conference with a Q&A session.
