Preserve line chart ornaments when you override the click event in dc.js? - data-visualization

Question

Still working on this visualization: https://ayyrickay.github.io/circulating-magazines/
I've got some good updates going, but one thing that's irking me is that, when somebody clicks on the line chart, it maintains state. For example, if I click on an issue, it runs this code to update both application state and crossfilter state
(chart) => {
chart.selectAll('circle').on('click', (selected) => {
state.circulationClicked = true
const clearFilterButton = document.getElementById('clearIssueFilterButton')
clearFilterButton.classList.remove('hide')
clearFilterButton.addEventListener('click', lineChart.unClick)
renderIssueData(selected)
samplePeriodEnd.filter(d => {
const currentIssueDate = moment.utc(selected.x)
const periodEnding = moment.utc(d)
const periodStart = moment.utc({'year': periodEnding.get('year'), 'month': periodEnding.get('month') === 5 ? 0 : 6, 'day':1})
if (currentIssueDate >= periodStart && currentIssueDate <= periodEnding) {
Object.assign(state, {currentIssueDate, periodStart, periodEnding})
return currentIssueDate >= periodStart && currentIssueDate <= periodEnding
}
})
state.totalSalesByState = salesByState.all().reduce((a, b) => ({value: {sampled_total_sales: a.value.sampled_total_sales + b.value.sampled_total_sales}}))
us1Chart.colorDomain(generateScale(salesByState))
us1Chart.customUpdate()
})
}
There's a lot going on here, but I'm frustrated because it seems like because I've overridden the default click, I've blown out some functionality that I wanted - specifically, I want the circle associated with the data point to stay in the viz.
Using the renderDataPoints method isn't right, because I only need the circle to stick around on click. I've also tried creating a moveToFront method to bring the circle to the front, but that hasn't worked for me. My problem seems to be that I'm not able to locate the circle and modify its properties in the click method itself. I get the data, but I don't get the HTML/SVG associated with the data point to modify it accordingly.
Rambly question as always, but would love some help sorting this out (and potentially getting it documented somewhere?)
