Description

Future visualization ideas for HTML report

Process-level comparison plot

  • Stacked bar chart showing energy consumption per process
  • X-axis: processes
  • Y-axis: energy
  • CPU and memory energy contributions visualized as stacked components
  • Interactive hover tooltips with additional process information
  • Optional ranking or sorting (e.g. by total, CPU, or memory energy)

Energy budget overview

  • Treemap-style visualization summarizing the overall energy distribution
  • Area proportional to total process energy
  • Visual indication of CPU vs. memory contribution (e.g. via color or shading)

Energy composition summary

  • Pie or donut chart showing overall CPU vs. memory energy shares
  • Provides a high-level overview of where energy is spent across the workflow

Contributor guide

Research direction
Explore the existing HTML report generation code in the plugin to understand the structure and available frameworks. Then design and implement the proposed visualizations using appropriate charting libraries (e.g., Chart.js, D3.js).
