Overview 🌐

In the realm of scientific data visualization, our interactive tool, Pcaso, empowers users to paint, explore, and share many-dimensional point-clouds with ease.By translating data into visually dynamic 2D plots, Pcaso enables researchers to make complex, multi-dimensional data accessible and interactive. However, the tool’s original designcould only handle a limited dataset size, making it challenging for users who needed to work with larger datasets for in-depth scientific exploration.

This project aimed to enhance the performance of the 2D data-painting tool by converting it to WebGL for high-speed, efficient data rendering.Additionally, we implemented R-shiny/R-studio compatibility, allowing users in the R ecosystem to port data seamlessly into Pcaso and configure visualizations with ease.With these upgrades, Pcaso became a more versatile, high-performing platform for data scientists and researchers worldwide.

Why Raman Ladhani and Computer n Electronics Lab? 🛠️

This project demanded a specialized skill set. Raman Ladhani and the team at Computer n Electronics Lab were selected for their expertise in high-performance web technologiesand extensive experience in creating efficient, data-driven applications. With a solid track record in the industry, Raman and the team were well-equipped to tackle thechallenges of migrating a D3-based tool to WebGL, ensuring seamless data rendering and adding R compatibility.

Challenges 🚧

• Performance Bottleneck: The existing tool was limited to around 20,000 data points. Handling larger datasets caused significant performance slowdowns, making the tool impractical for users needing hundreds of thousands to millions of points.
• R Compatibility: Pcaso lacked integration with R, limiting accessibility for researchers who predominantly work within the R environment. Creating a smooth data flow between R and Pcaso was crucial.
• System Down-Time: Due to backend dependencies, the tool occasionally experienced downtime. Ensuring stability and availability during and after the project was essential.
• Rendering Transformation: Moving from D3 to WebGL required a comprehensive overhaul of the rendering code while preserving the tool’s interactive capabilities and fluid user experience.

Solutions 💡

• Set up a sandbox server to host the current version of Pcaso, addressing backend dependency issues and ensuring the tool’s availability for testing and further development.
• Converted the rendering engine from D3 to WebGL, allowing Pcaso to handle much larger datasets with improved performance and speed.
• Developed a robust R-shiny/R-studio extension for Pcaso, enabling seamless import/export of data as .csv files and empowering R users to configure custom color schemes and plot interactions.
• Optimized code structure and implemented performance profiling to monitor and minimize resource consumption, reducing the chances of downtime and improving scalability.

Improvements 🔄

• Enhanced data handling capacity from 20,000 points to millions, allowing for broader application in scientific research and big data visualization.
• Optimized rendering efficiency, ensuring smoother interactions and faster data loading times for a more responsive user experience.
• Reduced dependency-related downtimes by implementing a stable server environment for continuous testing and development.
• Expanded accessibility for researchers by supporting .csv file imports from R, making it easier to use Pcaso in conjunction with R-studio/R-shiny.

Results 📊
