Project description
Easily create data visualization of static or streaming data
Get Started
pip install easycharts
Create EasyCharts Server
# charts.py
from fastapi import FastAPI
from easycharts import ChartServer
server = FastAPI()
@server.on_event('startup')
async def setup():
server.charts = await ChartServer.create(
server,
charts_db="test"
)
await server.charts.create_dataset(
"test",
labels=['a', 'b', 'c', 'd'],
dataset=[1,2,3,4]
)
Start Server
uvicorn --host 0.0.0.0 --port 0.0.0.0 charts:server
Update Data via API
