Meta Refresh 2014

On the construction of user interface on the web

Criteria for proposing sessions: You must be a practising web designer/developer, and must be able to show how your own work has advanced the state of the web in the past year. You are expected to present original work that your peers — this event’s audience — recognise as being notable enough to deserve a stage.

About Meta Refresh: Meta Refresh is a conference where Design and UI development converge. A beautiful experience on the web is a result of a deep understanding of your user and the nuances of the medium. Meta Refresh aims to be the platform where designers and UI developers exchange ideas and skills and learn from each other.

Format: This year’s edition spans four days, with two days of workshops and two days of conference. All days feature a single track.

We are accepting talks on:

  1. Front-end implementations, mainly workflow, processes, tools and automation,
  2. CSS, animation, UX, trends, and typography, and
  3. Short, crisp talks on front-end tricks.

Talks on implementation have to be about original work. While covering scalability and productivity aspects to explain implementation details, proposers must also explain who is the user and what is the context in which their product is being used. Therefore, how content and design were tailored in each specific instance.

We also invite workshop proposals on:

  1. Build systems such as Grunt
  2. CSS frameworks such as Bootstrap 3 and Foundation
  3. MVC/JS frameworks such as Angular
  4. Animations/UX

Workshops will be held on 12th and 13th February at the TERI auditorium in Domlur, Bangalore.

If you are excited about someone’s work and believe it deserves wider recognition, we recommend you contact them and ask them to submit a proposal.

Last date for submissions: 12 January 2014.
Confirmations: 15 January 2014 onwards.

There is only one speaker per session. Attendance is free for selected speakers. HasGeek will offer a grant to cover your travel to and accommodation in Bangalore from anywhere in the world for speakers delivering full sessions (30 minutes or longer). As our budget is limited, we will prefer speakers from locations closer home, but will do our best to cover for anyone exceptional. If you are able to raise support for your trip, we will count that as a speaker travel sponsorship.

Travel grants are reimbursed at the end of the conference. You are expected to make your own travel and stay arrangements. We will assist with hotel recommendations, visa letters and general advice on travel.

Commitment to open source

HasGeek believes in open source as the binding force of our community. If you are describing a codebase for developers to work with, we’d like it to be available under a permissive open source license. If your software is commercially licensed or available under a combination of commercial and restrictive open source licenses (such as the various forms of the GPL), please consider picking up a sponsorship. We recognize that there are valid reasons for commercial licensing, but ask that you support us in return for giving you an audience. Your session will be marked on the schedule as a sponsored session.

Non Accepted Proposals

If your proposal is accepted for a session > 30 minutes long, we will cover your event ticket. If your proposal is not accepted, you can buy a ticket at the same rate as was available on the day you proposed. We’ll send you a code.

Engineering custom visualisations with advanced d3.js

Submitted Jan 4, 2014

d3.js is a very complex library with a lot of functionality. That said, there are a lot of ready examples available on the Internet, which in turn promotes a culture of copy-paste-code. Hence, one ends up seeing recurring themes of the same charts - Sankey, Chord, Matrix, Force layout, etc. repeatedly.

The objective of this workshop help a d3 developer truly harness the power of d3.js to make custom visualisations.

Example: One of our client came to us with a list of 20-30 data points that they wanted to visualise. Instead of trying to forcefully fit them into any existing d3 chart, we conceptualised, designed and developed a custom d3 chart called as River Chart.


The idea of the talk to take a business problem and build a custom visualization from scratch. It will include advanced topics like:

  • Injecting real time data with KnockOut.js
  • How to read complex JSONs with Underscore, D3.set and D3.nest
  • SVG Path Generators: Area generator, Line generator, Arc generator, Bezier curve generator
  • Introduction to various D3 layouts and how to create a custom d3 layout
  • Using D3 components like Brush, Zoom, Drag, Context to improve interactivity
  • Leveraging D3 plugins like Sankey, Fisheye, JsonP, Key binding
  • Adding D3 transitions to introduce flash like animations
  • Combine power of visualization with simplicity of spreadsheets (EXTJS)


  • You should have basic knowledge of d3.js.
  • A computer with a) Chrome Browser b) Python WEB server c) Text-editor (even notepad will do).
