feat(visualization): add data visualization components to enhance data presentation

[berntpopp]

Description:
The application currently presents genetic variant data exclusively through tables and chips. While functional, this approach may not be optimal for data comprehension and user engagement. Adding appropriate data visualizations could make complex genetic information more intuitive and accessible.

Problem:

• Current data presentation relies heavily on tabular formats which can be dense and difficult to interpret
• Users may struggle to quickly identify patterns or relationships in the data
• The interface lacks visual elements that could help users understand data at a glance
• Complex genetic information could benefit from visual representations to improve comprehension

Desired Behavior:

1. Implement charts and graphs for quantitative data (scores, frequencies, etc.)
2. Add visual indicators for data quality and confidence levels
3. Create interactive visualizations that allow users to explore data relationships
4. Maintain existing table views while adding complementary visual representations
5. Ensure visualizations are accessible and responsive across devices

Implementation Work Plan:

• Research and select appropriate charting library (Chart.js, D3.js, or Vue-compatible options)
• Design visualization components for different data types:
  • Score distribution charts
  • Frequency comparison graphs
  • Quality indicators and confidence visualizations
  • Interactive data exploration tools
• Create reusable visualization components in src/components/
• Integrate visualizations into existing views (GeneView, VariantView, etc.)
• Add toggle options to switch between table and visualization views
• Implement responsive design for visualizations
• Add accessibility features (alt text, keyboard navigation)
• Update documentation and user guides

Affected Files & Logic:

• src/components/ - New visualization components
• src/views/GeneView.vue - Integration of gene-related visualizations
• src/views/VariantView.vue - Integration of variant-related visualizations
• src/views/BatchView.vue - Batch processing result visualizations
• package.json - Addition of visualization library dependencies
• CSS/styling files for visualization themes

Motivation:
Enhanced data visualization will improve user comprehension of complex genetic data, reduce cognitive load, and provide more engaging ways to explore variant information. This aligns with modern web application standards and improves the overall user experience for both novice and expert users.
