VizlyChart

A Python visualization library focused on performance and professional output quality.

Features

• Fast rendering: Optimized SVG generation with performance improvements over baseline matplotlib workflows
• Professional output: Clean typography with customizable fonts and spacing
• GPU acceleration support: Optional CuPy integration for data processing acceleration
• Multiple chart types: Line charts, scatter plots, bar charts, and 3D surfaces
• Engineering utilities: Specialized charts for technical applications

Installation

pip install vizlychart

For GPU acceleration (requires NVIDIA GPU):

pip install vizlychart[gpu]

For extended functionality with matplotlib integration:

pip install vizlychart[extended]

Quick Start

import vizlychart as vc
import numpy as np

# Generate sample data
x = np.linspace(0, 10, 100)
y = np.sin(x)

# Create and customize chart
chart = vc.LineChart()
chart.plot(x, y, label='sin(x)')
chart.set_title('Sample Chart')
chart.set_labels('X-axis', 'Y-axis')

# Save as SVG
chart.save('output.svg')

Performance

VizlyChart focuses on practical performance improvements:

• SVG-first rendering for scalable output
• Memory-efficient processing for large datasets
• Optional GPU acceleration for data preprocessing

Requirements

• Python 3.7+
• NumPy 1.24+

Optional dependencies:

• CuPy (GPU acceleration)
• Matplotlib (extended compatibility)
• SciPy (engineering functions)
