How to Set Initial Chart Type/Color By/Sort in Explorer React component

[Posvar]

After loading data into the explorer, I want to set it to a specific chart type, color by, and sort order.
Please refer to the explorerProps below, especially the mounted function.

I'm trying to load "grid" chart by default, with color by "toneCSS" and sort by "UniqueID".
Instead - the chart loads with chart type = "column" and color by and sort both default to a different value (alphabetic first attribute?).

import React, { useEffect, useState } from 'react';
import { Explorer } from '@msrvida/sanddance-explorer';
import { BrowserRouter as Router, useLocation } from 'react-router-dom';

function MainContent() {
    const location = useLocation();
    const [data, setData] = useState([]);
    const [explorer, setExplorer] = useState(null);

    useEffect(() => {
        // Simplified data fetching for brevity.
        fetch('/data.csv').then(response => response.text()).then(csvText => {
            // Parsing logic...
            setData(data);
        });
    }, []);
    
    const explorerProps = {
        mounted: (explorerInstance) => {
            if (!explorerInstance) return;            
            setExplorer(explorerInstance);
            if (data && data.length > 0) {
                explorerInstance.load(data, null, null, {
                    chart: 'Grid',
                    columns: {
                        color: 'ToneCSS',
                        sort: 'UniqueID'
                    }
                });
            }
        },
        // ... (other props)
    };

    return (
        <div className="app-container">
            {location.pathname === '/' ? 
                <Explorer {...explorerProps} /> : 
                <div>Loading...</div>
            }
        </div>
    );
}

function App() {
    return (
        <Router>
            <MainContent />
        </Router>
    );
}

export default App;

The 2nd parameter to the load function can return the initial insight:

explorerInstance.load(data, (columns)=>{
                    chart: 'Grid',
                    columns: {
                        color: 'ToneCSS',
                        sort: 'UniqueID'
                    }
                });

this worked - and had to change "Grid" to "grid" - case mattered! Thanks.
