{
    UseHighPerformance = true,
    EnableInteractivity = true
};

string systemId = await helper.InitializeSystem(config, options);
        

Creating Charts

            
                content_copy
            
            
var result = await helper.CreateChart(
    systemId: systemId,
    parameters: new ChartParameters
    {
        ChartType = "line",
        Data = new Dictionary
        {
            { "x", new[] { 1, 2, 3, 4, 5 } },
            { "y", new[] { 2.5, 3.5, 3.0, 4.0, 4.5 } }
        },
        Style = new StyleOptions
        {
            Colors = new Dictionary
            {
                { "line", Color.Blue },
                { "points", Color.Red }
            }
        },
        Interactions = new InteractionOptions
        {
            EnableZoom = true,
            EnableTooltips = true
        }
    }
);
        

Rendering Graphs

            
                content_copy
            
            
var result = await helper.RenderGraph(
    systemId: systemId,
    parameters: new GraphParameters
    {
        GraphType = "network",
        Nodes = new Dictionary
        {
            { "data", nodeData },
            { "size", 10 }
        },
        Edges = new Dictionary
        {
            { "data", edgeData },
            { "width", 2 }
        },
        Layout = new LayoutOptions
        {
            Algorithm = "force-directed",
            Parameters = new Dictionary
            {
                { "gravity", 1.0 },
                { "linkDistance", 100 }
            }
        }
    }
);
        

Best Practices

1. System Configuration

   • Set rendering type
   • Configure updates
   • Enable caching

2. Performance Optimization

   • Use appropriate renderers
   • Optimize data structures
   • Implement throttling
   • Cache results

3. Resource Management

   • Control memory usage

Error Handling

            
                content_copy
            
            
try
{
    await helper.CreateChart(...);
}
catch (DataVisualizationException ex)
{
    logger.LogError($"Visualization error: {ex.Message}");
    // Implement appropriate error recovery
}
