ZoomCharts at DevClub.lv: Developing a Javascript SDK
On January 15, 2015, ZoomCharts Co-Founder and CTO Viesturs Zariņš presented at DevClub.lv - a community of Latvian IT specialists that gather monthly and host free talks, presentations, and events to allow the local IT community to share knowledge, network, and communicate. Zariņš discussed the unique challenges faced in developing JavaScript SDK.
Here is a brief overview of his PowerPoint presentation on ZoomCharts, the world’s most interactive data visualization software that will support all your data presentation needs with incredible speed.
What is ZoomCharts?
What defines ZoomCharts advanced data visualization software? It is NOT another HTML5 charts library. It is:
- Interactive
- Fast
- Touch enabled
- Supports big data
A long time ago
DOS 6.2 allowed for:
- 320x240x8bpp
- Direct access to pixels on screen
- Assembler for performance
Today, the Web has finally caught up in the graphics department. Now, we have access to:
- Multiple browsers and rendering technologies
- Multiple resolutions
- Performance that varies by browser and device
Development setup:
- We write in JavaScript
- Commit to GitHub
- Build system in JavaScript
- Debug in Chrome
- Run automated tests
- Like WebStorm (and Vim)
Graphics:
Canvas (fast)
SVG (slow)
WebGL (>50%)
Interactive animations:
Zoom in and out of the graph, drag and drop data, all with your mouse or trackpad.
Graceful degradation:
High FPS (frames per second) lets you scale graphics with low image degradation.
Third party libraries:
- Raphael
- Hammer.js
- Leaflet
- Moment.js
Challenges:
- Responsive design: layouts can shift and look nice on desktop screens vs. not so nice on vertical, mobile screens
- Big screen resolutions: uses devicePixelRatio for sharp rendering, but no hardware acceleration beyond 2048x2048
- Safari compatibility: with 100% CPU, input events are blocked and browser locks up; strange code offers fixes
- HTML on canvas: DOM is slow; basic HTML markup must be parsed and rendered manually; text caching helps
Support:
- Process: TrialSupportBuy
- 1 day issue resolution
- #1 Tell me what I did wrong
- #2 Can you do…
Testing:
- Automated tests on every GIT push
Automatically:
- Compare images
- Record performance
- View errors in console
Interactive testing:
- Next step: record and playback
BrowserStack:
- Interactive mode
- Automated: Selenium API
Debugging:
Chrome Developer tools (F12)
- Debugging
- Profiling
- Timeline
Remote debugging available: developer.chrome.com/devtools/docs/remote-debugging
Future:
- More charts
- Extension API
- Memory allocation tracking
- WebGL
We are looking for statically-typed language:
- Error checking
- Performance
- Superior minification
- Easy to write and read
- Easy to call from JS
Building
Custom build script:
- Compile
- Minify
- Extract documentation
- Embed customer data

The Promise of Data: Will this Bring a Revolution in Health Care?
(March 22 to 27, 2015)
Credit: Salzburg Global Seminar/Ela Grieshaber
-----
It has now become an orthodoxy that we are moving into the age of 'Big Data'. This derives from ever increasing processing power and the vast surge in connectedness - with mobile technologies at the forefront and sensors in nearly all appliances, we are set to have 50 billion devices by 2020 connected in the cloud. It is argued that medical decisions can be truly evidence based, combining the most complete medical science with personal data, drawing where appropriate on 24/7 monitoring through mobile devices and patient reported outcome measures. Lifestyle advice and preventive action can be honed with ever greater accuracy. Benefits from treatment, its best timing, lowest cost, better understood risk, and more predictable side-effects should all flow from this data transition, bringing lower costs and higher value.
Corporations are competing in both investment and rhetoric. In 2013 Google launched a new subsidiary, Calico, which Larry Page claimed would represent 'moonshot thinking around health care', and there have been many similar claims. But how is all this justified? And how can we ensure that those advances which do arise from this new control of data truly benefit patients, rather than just the provider - and that this will be a benefit distributed across the social gradient and globally?
What are the risks on the horizon? Data is often siloed and used for competitive advantage. Protocols around privacy could be tested to destruction; for instance, it is possible to reverse engineer anonymized data to identify individuals. Forbes magazine even reports a case of medical data being sold on eBay. How might these risks be best mitigated?
This session will review the claims for Big Data and its true potential, and seek to identify the conditions under which it should yield the greatest benefits to patients and populations.
"The harmonization of technologically extending oneself consciousness, artificial intelligence and machine learning will reverse the failures of genetic predisposition & #limitation"- James Scott

Increase your SALES with ZoomCharts!
ZoomCharts had an excellent time participating in the TechHub Rīga March Meetup on March 12, 2015, taking place at Kaļķu street 12/14, Rīga, LV-1050, Latvia.
ZoomCharts CEO and Co-Founder Janis Volbergs gave an engaging presentation on the startup path from idea, to market, to investment, and what it takes to build a product from the ground up and take it to a new level.
How did it all start?
A problem was spotted. There were no visualization libraries delivering truly interactive charts for touch enabled devices that were capable of working with big data.
And so the idea emerged. This was the right time to build such a library.
Why?
Because touch screen displays will become a $31.9 billion dollar market by 2018. Smart mobile sensor devices were used by 1.75 billion people in 2014. The Big Data market will grow exponentially (from $8.8 billion in 2013), to $48 billion in 2018. HTML5 adoption is wide enough and touch enabled devices are powerful enough to generate interactive visualizations.
The ingredients for a successful startup include:
1. A grand vision. ZoomCharts’ vision is to become the number one SDK for interactive chart development in web and mobile apps.
2. A realistic plan for execution and getting your vision implemented.
3. (Most importantly) A team, able to see the grand vision and execute the plan.
ZoomCharts started small, but focused. A vision was set, a core team of professionals was assembled, and a detailed business plan was derived, which led to a €200,000 seed investment.
The product was created in less than a year, and launched public downloads and a shop in March 2014.
In less than a year, the customer list grew to include companies such as TCI Business Capital, Hewlett Packard, D8 Corporation, Proteus Enterprise, Narus, SwissLife, Taykey, Derivitec, Sensors, Click & Pledge, Ryan Scientific, Inc., Booxs, Frostbyte Consulting, Image webdesign, Norbit, Helm, Zengo, Ense Group, RCS, Helbling, Loonloon, Fractalerts, Thinktecture, bitmama, KeeSystem, Trulia, Maxfone, and many more.
Increase your SALES with ZoomCharts!
ZoomCharts started with a €0 investment in dedicated marketing. A follow up investment of €500,000 raised in November 2014 enabled us to scale our team from 3 to 11, and get us moving forward fast.
Today, the ZoomCharts team has grown from 3 to 11, and has raised a total investment of €700,000. We’ve reached 40 paying customers, and growing, and there have been over 700 trials started, and growing.
Current challenges include brand building, marketing and sales, and incorporation into the US, including patents.
Despite the challenges, ZoomCharts is excited about the company’s future, which includes plans such as:
1. Raise €5-7 million to massively expand sales and marketing.
2. Expand the team to 40+ within the next two years.
3. Launch multiple SAAS solutions that would let a much wider audience take advantage of the benefits ZoomCharts provides.
We are proud to be part of ZoomCharts, and we are glad to hear that our customers love ZoomCharts as much as we do!
