Issues with displaying the graph generated using table in outlook

I’m using the following code to generate a graph where the widths are calculated dynamically based on current and projected values, both of which are also dynamic. While the graph displays correctly in an online HTML compiler, it does not render properly in Outlook. Please help me resolve this issue.

<table style="background-color: #343a42; border-radius: 10px; padding: 15px;" width="100%" border="0" cellspacing="0" cellpadding="0">
    <tbody>
        <tr style="width: 100%;">
            <td style="color: #ffffff; font-size: 12px; padding-left: 16px; padding-bottom: 4px; width: 70%;">Measurement in Gigabytes (GB)</td>
        </tr>
        <tr style="width: 100%; display: flex;">
            <td style="font-size: 12px; width: auto; writing-mode: vertical-rl; float: left; color: #fff; text-align: center;">AT&T</td>
            <td style="width: 100%;">
                <table width="100%" border="0" cellspacing="0" cellpadding="0">
