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

2455 Hayward Street in Ann Arbor, MI. on March 31, 2019.
Mi-TEE (Miniature Tether Electrodynamics Experiment) is a proof of concept run by Professor of Electrical Engineering and Computer Science Brian Gilchrist and is a part of the University of Michigan's Multidisciplinary Design Program that will help space explorers better understand the feasibility of a novel propulsion technology – miniature electrodynamic (ED) tethers – as means to provide propellantless propulsion to new classes of very small satellites known as picosats and femtosats.
A NASA space mission for MiTEE - 1 is planned for the first quarter of 2020.

On the 4th & 5th October 2016, leading international thinkers in the areas of Data, Predictive Models, Technology and Decision making gathered at the RDS, Dublin, for Predict 2016. The speakers, many of whom I managed to photograph, discussed the latest progress in Predictive Modelling and its future – from Data to Software and Hardware technology, plus Predictive Modelling methods and the best examples of Data-driven Decision-making.
The organisers kindly invited me to the Predict event at the RDS but as I arrived a bit early I took few backstage or behind the scenes shots. In case your are interested I used a Sony A7RM2 coupled with a Sony 29-135 full frame lens. The lens does attract a lot of attention which does allow me to to have interesting people … volunteers, students from Brazil, photographers etc.
