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

EFI Planted Forests Facility Summer School, Palencia’18
Organised by iuFOR and EFI's Planted Forest Facility (formerly EFIATLANTIC)
Palencia (España)

Hosted by iuFOR ( Universidad de Valladolid & INIA) and Escuela Técnica Superior de Ingenierías Agrarias, Universidad de Valladolid
Target public:
Graduate students (Masters and PhD) in forest sciences, forest geomatics or data science
Practitioners and IT staff from forest companies, administrations and R&D institutes
Target outcomes:
By the end of the course the participants will have a comprehensive overview of forest data management and analysis including relevant R skills to develop forest models at stand and tree levels and a foundation on cloud simulation of forest systems.
Rationale:
Forest management is facing different challenges due to the magnitude of the current environmental problems (climate change, invasive species, biodiversity crisis, etc.) and the growing demand for goods and services by the society.
Furthermore, the current Knowledge Society paradigm requires professionals to integrate different skills into their specific domain effectively; for example, the management of big databases, including analysis, modeling and decision making.
Although there are some local initiatives such as the DataForest MSc programme at University of Valladolid this specific type of education and training in data management and analysis is not available to forest managers and forest scientists. In general personnel involved in forest management and its environs have a good working knowledge of forest management systems and methods.
However this knowledge could be further enhanced by skills in other complimentary fields, such as database management, computer programming, data analysis, decision making through operational research techniques, geographic information systems and remote sensing.
