Grazie mille,purtroppo l html mi è stato fornito cosi dal professore,e non posso modificare nulla nell html

la struttura interessata e' questa

<div id="figure_1" class="picture">
                <p class="img_block">
                    <img src="#cur_data" class="horizontal_bar_chart" alt="Let's graph it!"></img>
                </p>
                <p class="caption">Caption of the figure.</p>
            </div>
            <div id="figure_2" class="picture">
                <p class="img_block">
                    <img src="#cur_data" class="vertical_bar_chart" alt="Let's graph it!"></img>
                </p>
                <p class="caption">Caption of the figure.</p>
            </div>
            <div id="figure_3" class="picture">
                <p class="img_block">
                    <img src="#cur_data" class="pie_chart" alt="Let's graph it!"></img>
                </p>
                <p class="caption">Caption of the figure.</p>
            </div>
            <div id="figure_4" class="picture">
                <p class="img_block">
                    <img src="#cur_data" class="horizontal_bar_chart" alt="Let's graph it!"></img>
                </p>
                <p class="caption">Caption of the figure.</p>
            </div>
            <div id="figure_5" class="picture">
                <p class="img_block">
                    <img src="#cur_data" class="vertical_bar_chart" alt="Let's graph it!"></img>
                </p>
                <p class="caption">Caption of the figure.</p>
            </div>
            <div id="figure_6" class="picture">
                <p class="img_block">
                    <img src="#cur_data" class="pie_chart" alt="Let's graph it!"></img>
                </p>
                <p class="caption">Caption of the figure.</p>
            </div>
        </div>

la sostituzione del và fatta su ogni p con class img_block e creare un grafo diverso in base alla classe delle img
