​
Why Choose Cristalyse?

Familiar syntax if you’ve used ggplot2 or plotly. Build charts by layering data, mappings, and geometries instead of wrestling with rigid chart widgets.
Leverages Flutter’s rendering engine, not DOM manipulation. GPU-accelerated performance that handles large datasets without breaking a sweat.
One codebase → Mobile, Web, Desktop, all looking identical. No platform-specific chart libraries or inconsistent rendering.
Dual Y-axis support, stacked/grouped bars, interactive tooltips, SVG export, and custom theming for business-grade dashboards.

​
Quick Example

Here’s how easy it is to create your first chart: 
import 'package:cristalyse/cristalyse.dart';
import 'package:flutter/material.dart';

class MyChart extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    final data = [
      {'x': 1, 'y': 2, 'category': 'A'},
      {'x': 2, 'y': 3, 'category': 'B'},
      {'x': 3, 'y': 1, 'category': 'A'},
      {'x': 4, 'y': 4, 'category': 'C'},
    ];

    return CristalyseChart()
      .data(data)
      .mapping(x: 'x', y: 'y', color: 'category')
      .geomPoint(
        size: 8.0,
        alpha: 0.8,
        shape: PointShape.triangle,
        borderWidth: 1.5,
      )
      .scaleXContinuous()
      .scaleYContinuous()
      .theme(ChartTheme.defaultTheme())
      .build();
  }
}
Result: A beautiful, animated scatter plot that works identically on iOS, Android, Web, and Desktop.
