Why does the chart_Series chart look blurry in Shiny?

Hi!
Why does the chart look blurry in shiny and how can I fix it?

ui <- fluidPage(
plotOutput("Chart")
)

server <- function(input, output) {
output$Chart <- renderPlot({
chart_Series(symb)
})
}

shinyApp(ui, server)

The question was asked in [more detail here.](https://stackoverflow.com/questions/76120449/why-does-the-chart-series-chart-look-blurry-in-shiny)

Start with the chart_Series(symb) call inside the Shiny renderPlot block and compare it with the plotOutput("Chart") setup. Reproduce the blurry output, then review the linked Stack Overflow question for additional context. Done means the chart renders clearly in the Shiny application, with the cause and fix documented.
