Installation

pip install zengeld-canvas

Quick Start

from zengeld_canvas import Chart, Bar

# Create sample OHLCV data
bars = [Bar(1703721600, 100.0, 105.0, 98.0, 103.0, 1000.0)]

# Build chart
chart = Chart(800, 600)
chart.bars(bars)
chart.candlesticks()
chart.sma(20, "#2196F3")

# Render to SVG
svg = chart.render_svg()

# Save to file
with open("chart.svg", "w") as f:
    f.write(svg)
