    <h1>PHP Interval Graph demo</h1>
</header>
<p>
    PHP Interval Graph is a small utility to manipulate and
    display arrays of intervals.
</p>
<a href="https://github.com/vctls/php-interval-graph">
    https://github.com/vctls/php-interval-graph
</a>
<h2>How it works</h2>
<p>
    Here are three overlapping date intervals.
    Each one has a linked rate, displayed as a percentage when hovering it.
    <br>They are all displayed over the same period of time, which has no rate.
</p>
<div style="margin-bottom: 2px"><?= $overlapped1 ?></div>
<div style="margin-bottom: 2px"><?= $overlapped2 ?></div>
<div style="margin-bottom: 2px"><?= $overlapped3 ?></div>

<p>
    Gathered on the same graph, they are displayed as follows.
</p>
<?= $overlapped ?>

<h2>More examples</h2>
<p>
    Overlapping intervals with a couple null intervals.<br>
    The first null interval overlaps a non null one.
    This cuts the non null interval, while the weight remains the same.<br>
    The second null interval is implicit.
    It is simply the gap between the two last intervals.
</p>
<div style="margin-bottom: 2px"><?= $withNull1 ?></div>
<div style="margin-bottom: 2px"><?= $withNull2 ?></div>
<div style="margin-bottom: 2px"><?= $withNull3 ?></div>
<div style="margin-bottom: 2px"><?= $withNull4 ?></div>
<br>
<?= $withNullIntervals ?>


<h2>Custom value types</h2>
<p>
    The following graph takes arrays of two values
    and displays them as fractions.<br>
    In order to use custom value types, you need to set the custom functions
    that will aggregate the values, convert them to numeric values and strings.
</p>
<?= $fract ?>

<p>
    The same graph, truncated between <?= $date1->format('Y-m-d H:i:s') ?>
    and <?= $date2->format('Y-m-d H:i:s') ?>.
    <?= $truncated ?>
</p>

<p>
    A graph with three isolated dates, shown as black bars.
    <br>One of the dates goes beyond all intervals.
    <?= $withDates ?>
</p>
<p>
    A bunch of random graphs, this time generated through JavaScript:
    <br>
</p>
<div id="random"></div>
<script>
    'use strict';
    const graphs = JSON.parse('<?= json_encode($intvGraphs) ?>');
    const el = document.getElementById('random');

    try {
        graphs.forEach(function (graph) {
            let html = document.createRange().createContextualFragment(intvg(graph));
            el.appendChild(html);
        });
    } catch (e) {
        el.innerHTML = 'The JavaScript function uses ES6 string literals. Sorry not sorry, IE.';
