renderer = GraphRenderer()
rendered_chart = renderer.render(chart_data)
Example 2: Line Chart
// Sample usage of the Graph & Chart Renderer for a line chart in Node.js
const chartData = {
type: 'line',
title: 'Stock Prices Over Time',
dataPoints: [
{x: 'Mon', y: 100},
{x: 'Tue', y: 120},
{x: 'Wed', y: 90},
{x: 'Thu', y: 150}
]
};
const renderedChart = renderer.render(chartData);
FastAPI Endpoint Example
# Example FastAPI endpoint using the Graph & Chart Renderer
from fastapi import APIRouter, Depends
from pydantic import BaseModel
from typing import Optional
router = APIRouter()
class ChartDataRequest(BaseModel):
type: str # 'bar', 'line', or 'pie'
title: str
data_points: list[dict]
x_label: Optional[str] = None
y_label: Optional[str] = None
colors: Optional[list[str]] = None
font_size: Optional[int] = None
@router.post("/render-chart")
async def render_chart(data: ChartDataRequest):
renderer = GraphRenderer()
return {"chart": renderer.render(data)}
React UI Integration Example
# Example React component using the Graph & Chart Renderer
import React, { useState, useEffect } from 'react';
import { BarChart, LineChart, PieChart } from 'some-visualization-library';
const ChartRenderer = () => {
const [chartData, setChartData] = useState(null);
useEffect(() => {
fetch('/api/render-chart', {
method: 'POST',
headers: {
'Content-Type': 'application/json'
},
body: JSON.stringify({
